Description

The Summer School in Mathematics 2022 (Institut Fourier, Grenoble) will take place from June 13th to July 1st, 2022 and will be dedicated to Cohomology, Geometry and Explicit number theory (COGENT).

It will be a hybrid event with both in-person and online participation.

The goal of this school is to introduce young mathematicians to some recent developments in the field of cohomology of groups, with a focus on arithmetic groups, from geometrical, topological and computational aspects with applications to number theory. We also want to promote greater interaction among researchers and PhD students,​ and strengthen the COGENT network through new collaborations.

The first two weeks are dedicated to mini-courses and mini-workshops around some computational tools and new computational techniques, as well as short term team projects.

The third week will be devoted to a workshop on COGENT featuring both young researchers and leading specialists.

There will also be an "Illustrating mathematics'' event with an art exhibitions showcasing artistic visuals related to the geometries of arithmetic groups.

Galois representations, automorphic forms and L-functions

CIRM

Meeting Type: conference

Contact: Jaclyn Lang

Description

The relationship between L-functions, automorphic forms and Galois representations is a central theme in Number Theory. Some of the most intriguing aspects of this relationship are the conjectural links between analytic properties of L-functions and arithmetic invariants of varieties over number fields. These links, known as Bloch–Kato conjectures, can be seen as a vast generalization of the class number formula for Dedekind zeta-functions and the conjecture of Birchand Swinnerton-Dyer for elliptic curves. The only known way to attack these conjectures is to relate the underlying geometric objects to automorphic forms using the Taylor–Wiles method and to study special values of L-functions via Iwasawa theory. The latter approach requires an extensive development of the theory of p-adic L-functions. From this point of view, the p-adic analogs of the Bloch–Kato conjecture include the p-adic Beilinson Conjectures, formulated by Perrin-Riou, and the Main Conjectures of Iwasawa theory. The last two decades have seen spectacular progress in the use of p-adic methods to solve new instances of the Bloch-Kato Conjectures. The method of Euler systems, initially invented by Kolyvagin and Kato in the context of modular forms, was partially extended to some new situations (Rankin–Selberg L-functions, triple products, symplectic groups) and applied to Gross-Stark conjectures. The generalization of the Ribet–Wiles approach to some unitary groups lead to the proof of the Greenberg Main Conjecture for a large class of modular forms. The theory of Selmer complexes generalized and simplified algebraic aspects of the theory, and found impressive appli-cations to the Parity Conjecture. Classical constructions of p-adic L-functions were extended to algebraic groups of higher ranks. Also the realm of interaction between automorphic forms and Galois representations is in full bloom, and recently established R = T theorems have led to proofs of generalizations of Serre’s Modularity Conjecture and the Sato-Tate Conjecture. The aim of the conference is to bring together leading experts and emerging scientists, to report on the latest developments, to foster scientific exchanges, to initiate new interaction and collaboration, and thereby contribute to the scientific advancement of the field.

Contact: Gabriele Mondello

Description

The workshop will be devoted to the study of surfaces with special metrics with singularities of conical type.

In particular it will focus on the case of spherical metrics, namely Riemannian metrics of curvature 1. Such metrics have been studied from many points of view, using tools coming from synthetic geometry, complex analysis and partial differential equations.

The aim of the meeting is to bring together people with different backgrounds to discuss recent developments, techniques and open questions in the areas of spherical surfaces with conical points, projective structures with singularities and their monodromy, solutions of the singular Liouville equation, polyhedral spherical surfaces, polygonal linkages.

Description

RNT-3 will be a remote collaborative research experience supported, in part, by the American Institute for Mathematics for the weeks of June 20 - July 1. The goal is for participants to learn new math, get to know colleagues, and have a joyful, affirming research experience. Workshop meetings will be planned around our busy schedules so that we can work on exciting research while also keeping up with our teaching and family responsibilities. Team leaders have planned projects for participants to work on during the workshop. You can read more about the projects here.

To ensure that all participants can share in this joyful research experience, we ask that all who apply to participate be committed to equity and justice. We will also make time to imagine a different way to do math: How could research seminars, postdoc positions, and graduate school be transformed to be comfortable to everyone? We will have a code of conduct for the workshop, which you can read here.

To participate in our workshop, please apply by the end of the day on May 15, 2022 The application is here.

RNT aims to foster diversity; we particularly encourage applications from historically underrepresented people in mathematics (including Black and Indigenous people, people of color, women, LGBTQ+ members of the community, and people with disabilities), scholars at undergraduate institutions, and in general scholars at all stages of their career who believe they would benefit from this experience. Please share this announcement with any groups, students, post docs, or scholars who might be interested in participating in this workshop.

Meeting Type: conference

Contact: see conference website

Description

On April 6, 1972 a young graduate student named Hugh Montgomery and the world-renowned mathematical physicist Freeman Dyson had a conversation in the tearoom at the Institute for Advanced Study which led to a fusion of two disparate fields and an intellectual revolution that is stronger than ever today. Montgomery and Dyson discovered that the zeros of the Riemann zeta-function, important for understanding prime numbers, seem to obey the same distribution patterns as the eigenvalues of large random unitary (or hermitian) matrices, which had been extensively studied by physicists, especially to model the interactions within large atomic nuclei. This stunning connection has held up to extensive numerical and theoretical tests over the intervening years and has been extended to give random matrix models for the low lying zeros of families of L-functions and for the moments and distribution of values of the L-functions in these families and to analogous families over function fields. This conference will bring together 130 mathematical scientists to a meeting that will highlight the progress and the state of the art of results at the nexus of these two fields and will underline the questions most pertinent for further research.

Homotopy theory with applications to arithmetic and geometry [European side]

Meeting Type: twinned conference (see description)

Contact: Aaron Mazel-Gee

Description

The field of homotopy theory originated in the study of topological spaces up to deformation, but has since been applied effectively in several other disciplines. Indeed, homotopical ideas lead to the resolution of several long-standing open conjectures, for instance on smooth structures on spheres, the moduli of curves, and the cohomology of fields. More recently, Bhatt, Morrow, and Scholze used homotopical methods to compare different cohomology theories for algebraic varieties, thereby resolving open questions in arithmetic geometry. In a similarly arithmetic vein, Galatius and Venkatesh initiated the study of Galois representations with homotopical means, whereas Clausen and Scholze revisited the foundations of analytic topology. These and other recent developments in the interface of arithmetic and topology opened up new lines of attack towards classical open questions, which sparked a wide range of current research activities. This conference intends to survey some of the most spectacular recent advances in the fields, thereby paving the way to new developments and future interactions. Our goal is to foster scientific exchange and collaboration between established researchers, emerging leaders, early career mathematicians, and graduate students.

This will be a split transatlantic conference taking place at the Fields Institute in Canada and the Max Planck Institute for Mathematics in Germany, with videoconferencing connections in place to help collaboration.

Description

Spec(Q¯¯¯¯) is the first conference to celebrate and promote research advances of LGBT2Q mathematicians specialising in algebraic geometry, arithmetic geometry, commutative algebra, and number theory. This conference capitalises on recent thematic program successes in algebraic geometry at Fields, the Thematic Program on Combinatorial Algebraic Geometry (July 1 - December 31, 2016) and the Thematic Program on Homological Algebra of Mirror Symmetry (July 1 - December 31, 2019). Spec(Q¯¯¯¯) will create an empowering and engaging environment which provides LGBT2Q visibility in algebraic geometry, will support junior LGBT2Q academics, and will crystallise new collaborative networks for participants. Algebraic geometry, classically, is the study of the geometry of solutions of polynomial equations; through modern advances it has become an intersectional mathematical field, drawing from various aspects of algebra, number theory, geometry, combinatorics and even mathematical physics. This conference aims to highlight strong mathematical research in a wide array of algebraic geometry, broadly defined. The conference will feature some plenary talks by world-leading researchers from a range of areas of algebraic geometry. To facilitate new connections across the various threads of algebraic geometry, plenary talks at Spec(Q¯¯¯¯) will be aimed a general algebro-geometric audience.

This activity will bring together mathematicians spanning all academic ranks to create ideal networking and mentorship for LGBT2Q academics while disseminating key achievements of trans and queer algebraic geometers. Queer and trans academics often have a diffcult experience developing key collaborations and networks of trusted colleagues. Each research connection, grant, and application involves a conscious decision of how much of one’s queer/trans identity to disclose. This conference provides a safe space to develop ones network while removing these barriers. In such spaces, one can discuss mathematics with new colleagues while unbridled with many societal challenges that they face in mathematical communities. When a mathematician feels free to be themselves in all ways, they are able to immerse themselves in creative mathematical thought.

University of Colorado Boulder
Boulder, CO; USA

Meeting Type: summer school

Contact: Agnes Beaudry, Kate Ponto, Dylan Wilson

Description

Description The goal of this summer school is to introduce participants to tools and ideas from algebraic topology and homotopy theory that are used in the study of fixed point theory. The workshop will be centered around mini-courses, both on classical fixed-point theory and on modern techniques such as duality theory, spectra, and trace methods in algebraic K-theory.

The intended audience for this summer school should be familiar with the material in Hatcher (except the appendices). This reflects our goal that the school be accessible to second and third year students with an interest in algebraic topology. The school will be structured around a few mini-courses, which will run in an active-learning style.

Description

new description:

It has been almost 45 years since the influential summer school held in Corvallis, Oregon in 1977 brought together the leading experts of the Langlands program and defined the research agenda in this area for subsequent decades, at the same time inspiring and enabling several generations of young researchers to join in this exciting journey. This 3-week IHES summer school aims to do the same for the next phase of development in the Langlands program.

Recent decades have brought tremendous progress on the project of endoscopy, the extension of the Langlands program to the “relative” setting of spherical varieties and other related spaces, numerous successful “explicit” methods (such as the theta correspondence) to construct functoriality, novel ideas “beyond endoscopy”, and arithmetic applications of both the theta correspondence and the relative trace formula to the study of special cycles and their generating series. Ideas from the geometric Langlands program have begun impacting and enriching the classical Langlands program in significant ways. In particular, the idea that the “space of Langlands parameters” is not just a set, but a (putative) geometric space, can be used to organize a lot of developments around reciprocity, including the Taylor–Wiles method, derived structures, the Langlands correspondence over function fields, and the geometrization of the local Langlands conjecture.

The summer school will attempt to bring these exciting new directions together and explore their interactions.

Description

CALL FOR PAPERS The study of the relationship between music and mathematics has a thousand-year-long history which predates Pythagoras. Mathematics and music share a common basis of language and creativity. From the theory of tuning systems and temperament to physical acoustics, from harmonic analysis to spectrograms, from the structures of rhythms and pulses to the continuous stretching of the laws of harmony and the exploration of the musical forms carried out by contemporary composers, all elements of music lead to an immediate connection to mathematics. Established and recent research has witnessed the use of set theory to describe how musical objects are related and organised, the use of group theory in the context of transformational analysis of tonal and atonal compositions, the application of Grassmannians to the study of temperaments, and the investigation of category theory, topology and differential geometry to provide a basis of music theory. The Institute of Mathematics and its Applications is glad to announce the launch of the first IMA conference on "Mathematics in Music", to take place on 13-15 July 2022 at the Royal College of Music, London. The conference focusses onto the exploration of the connections between mathematics and music, in particular current developments of music theory, music performance, music perception and music technology based on or inspired by mathematical applications and concepts, including (but not limited to) category theory, group theory, topology, differential geometry, combinatorics, analysis, acoustic theory, as well as artificial intelligence, deep learning, language processing and coding. The conference is aimed at mathematical researchers working at the frontier between mathematics or computation with music theory, musicology, music performance, sound engineering and composition, as well as at musicologists or computational musicologists, performers and composers using quantitative tools and formal methods from mathematics in their investigation and professional practice of music. Invited Speakers: Prof Emily Howard, Royal Northern College of Music Prof Guerino Mazzola, University of Minnesota Prof Geraint Wiggins, Vrije Universiteit Brussel & Queen Mary University of London Moreno Andreatta, CNRS Director of Research at IRMA Call for Abstracts: Abstract Submission of 300 words by the 31 March 2022. via https://my.ima.org.uk.

Description

Over the last decade, there has been a wealth of new applications of homotopy-theoretic techniques to Floer homology in low-dimensional topology and symplectic geometry, including Manolescu’s disproof of the high-dimensional Triangulation Conjecture and Abouzaid-Blumberg’s proof of the Arnol’d Conjecture in finite characteristic. Conversely, results in Floer theory and categorification have opened new directions of research in homotopy theory, from string topology to S-Lie algebras. The goal of this workshop is to introduce researchers in Floer theory to modern techniques and questions in homotopy theory and, conversely, introduce researchers in homotopy theory to ideas underlying Floer theory and its applications.

The goal of this summer school is to introduce the participants to motivic integration and some of its applications. It is mainly aimed at PhD students and Postdocs who do work in an area around algebra and/or geometry, but who have not yet had any prior contact to this motivic integration. There will be three minicoures, which will explain the necessary tools and background material, give down-to-earth motivation and examples, and which will end with some interesting applications. In addition, there will be around ten one-hour talks about current research related to motivic integration. The summer school is part of the program of the DGF-funded research training group.

IMANewLecturers2022

Through a community initiative supported by the Institute of Mathematics and its Applications, the Isaac Newton Institute for Mathematical Sciences and the Heads of Departments of Mathematics Sciences (HoDoMS) and endorsed by the Royal Statistical Society and the London Mathematical Society, we are delighted to announce that in September 2022 the two‐day Induction Course for lecturers new to teaching mathematics and statistics within Higher Education will once again take place. Whilst arrangements may still be subject to change due to the ongoing Covid‐19 situation and any future Government guidance, we are currently preparing for the Induction Course to be delivered as an in‐person only activity to maximise the opportunities for informal networking and discussion that have long formed a highly‐valued part of this meeting.

The Induction Course for New Lecturers in the Mathematical Sciences has been designed by the mathematics community so that it is ideally suited for anyone who is new to or has limited experience teaching mathematics or statistics within UK higher education. It will be delivered by individuals with significant experience of teaching in the mathematical sciences and will focus upon the specific details and issues that arise in mathematics and statistics teaching and learning within higher education including topics such as:

• Lecturing. • Supporting student learning. • Making teaching interactive. • Assessment, examinations and feedback. • Linking teaching & research. • Using technology to enhance teaching and learning. • Using examples and mathematical problem solving. • Teaching statistics and its applications.

Additionally, there will be significant opportunities for delegates to discuss their own ideas, challenges and experiences with the session facilitators so that individual queries can be answered.

In the past, attendance has been recognised as contributing towards some introductory institutional programmes in learning and teaching for new staff, and for the 2022 Induction Course accreditation will be provided through the Institute of Mathematics and its Applications relative to the UK Professional Standards Framework for Teaching and Supporting Learning in Higher Education.

Timing The Induction Course takes place at the Isaac Newton Institute for Mathematical Sciences at the University of Cambridge and commences mid‐morning on the 14 September, and ends late‐afternoon on the 15 September. Accommodation will be offered at the University of Cambridge on the evening of the 14 September for any delegates who attend in person, although any in‐person attendance will be dependent upon the Covid‐19 situation at the time. As such, we reserve the right to make necessary changes to arrangements in response to Government legislation and guidance.

Session Facilitators Those leading the sessions at the Induction Course are all experienced teachers of mathematics within UK higher education. They include:

• Lara Alcock (Loughborough University) • Michael Grove (University of Birmingham) • Rachel Hilliam (Open University) • Kevin Houston (University of Leeds) • Joseph Kyle (University of Birmingham) • Steve Otto (The R&A) • Chris Sangwin (The University of Edinburgh) • Louise Walker (The University of Manchester) • John Mason (Open University) • Ulrike Tillmann (Isaac Newton Institute for Mathematical Sciences)

Meeting Type: undergraduate school

Description

The Preliminary Arizona Winter School (PAWS) is a virtual program on topics related to the upcoming AWS, with an intended audience of advanced undergraduate students and junior graduate students.

PAWS 2022 will consist of two concurrent six-week lecture series.

  • Ronnie Nagloo: Introduction to model theory with applications

    Model theory is a branch of mathematical logic dealing with abstract structures, historically with connections to other areas of mathematics. The developments, over the past several decades, have allowed for a strengthening of those connections as well as new striking applications to areas such as diophantine and analytic geometry, algebraic differential equations, and combinatorics. This course will serve as an introduction to the basics of model theory, with a view towards some of the above applications.

  • Padmavathi Srinivasan: Heights in Diophantine geometry

    The height of a rational number is a measure of its arithmetic complexity. For example, although the numbers 5 and 500000/100001 are close, the second is arithmetically more complex, and has a much larger height. The height of a rational number is easy to define -- it is simply the maximum of the absolute value of the numerator and the denominator when the number is expressed in lowest form. It is not immediately clear how one can extend this definition to more general algebraic numbers such as the squareroot of 2. In this series of lectures, we will develop the theory of heights of algebraic numbers, and present "Weil's height machine" for defining heights more generally for solutions to systems of polynomial equations in algebraic numbers (i.e., heights of algebraic points on varieties).

    Height functions are a key tool in proving many important finiteness theorems in Diophantine Geometry. The main property of height functions is that there are only finitely many points of bounded height and degree on any given variety. Understanding how quickly the number of points grow as the height grows for various classes of varieties is an active area of research in number theory today! As an application of the theory of heights, we will prove the Mordell--Weil theorem for elliptic curves, namely that the set of rational solutions to cubic equations such as y^2 = x^3 - 2x + 2 is finitely generated.

Registration: You can apply for the program here. The deadline to apply is July 15th, 2022.

Each lecturer will be accompanied by graduate student assistants, who will be in charge of writing weekly problem sets and facilitating weekly, hour-long problem solving and discussion meetings with groups of students. Recommended background for the program is a first course in abstract algebra.

The school will feature an online (Zulip) discussion board where students can ask questions and interact with the speakers and assistants outside of scheduled meeting times.

We will facilitate additional virtual events, some purely social to build a community, and some more structured sessions on timely and pertinent topics like "What is graduate school in Math like?", "Tips for applying to graduate school this Fall," "How do I navigate the first year of graduate school?" "How do I look for an thesis advisor?", "How to get the most out of the upcoming AWS."

We encourage undergraduate students to take their PAWS course as an independent study with a faculty member at their home institution.

Meeting Type: conference

Description

The fundamental conjecture of Birch and Swinnerton-Dyer relating the Mordell–Weil ranks of elliptic curves to their L-functions is one of the most important and motivating problems in number theory. It resides at the heart of a collection of important conjectures (due especially to Deligne, Beilinson, Bloch and Kato) that connect values of L-functions and their leading terms to cycles and Galois cohomology groups.

The study of special algebraic cycles on Shimura varieties has led to progress in our understanding of these conjectures. The arithmetic intersection numbers and the p-adic regulators of special cycles are directly related to the values and derivatives of L-functions, as shown in the pioneering theorem of Gross-Zagier and its p-adic avatars for Heegner points on modular curves. The cohomology classes of special cycles (and related constructions such as Eisenstein classes) form the foundation of the theory of Euler systems, providing one of the most powerful methods known to prove vanishing or finiteness results for Selmer groups of Galois representations.

The goal of this semester is to bring together researchers working on different aspects of this young but fast-developing subject, and to make progress on understanding the mysterious relations between L-functions, Euler systems, and algebraic cycles.

Description

Number Theory concerns the study of properties of the integers, rational numbers, and other structures that share similar features. It is a central branch of mathematics with a well-known feature: it is often the case that easy-to-state problems in number theory turn out to be exceedingly difficult (e.g. Fermat’s Last Theorem), and their study leads to groundbreaking discoveries in other fields of mathematics.

A fundamental theme in number theory concerns the study of integer and rational solutions to Diophantine equations. This topic originated at least 3,700 years ago (as documented in babylonian clay tablets) and it has evolved into the highly sophisticated field of Diophantine Geometry. There are deep and fruitful interactions between Diophantine Geometry and seemingly distant fields such as representation theory, algebraic geometry, topology, complex analysis, and mathematical logic, to mention a few. In recent years, these connections have led to a large number of new results and, specially, to the partial or complete resolution of important conjectures in the field.

While the study of rational solutions of diophantine equations initiated thousands of years ago, our knowledge on this subject has dramatically improved in recent years. Especially, we have witnessed spectacular progress in aspects such as height formulas and height bounds for algebraic points, automorphic methods, unlikely intersection problems, and non-abelian and p-adic approaches to algebraic degeneracy of rational points. All these groundbreaking advances in the study of rational and algebraic points in varieties will be the central theme of the semester program “Diophantine Geometry” at MSRI. The main purpose of this program is to bring together experts as well as enthusiastic young researchers to learn from each other, to initiate and continue collaborations, to update on recent breakthroughs, and to further advance the field by making progress on fundamental open problems and by developing further connections with other branches of mathematics. We trust that younger mathematicians will greatly contribute to the success of the program with their new ideas. It is our hope that this program will provide a unique opportunity for women and underrepresented groups to make outstanding contributions to the field, and we strongly encourage their participation.

Description

The theme of the conference will be explicit and computational methods in number theory and arithmetic geometry in a broad sense. The format will include scientific talks as well as time for informal collaboration and for coding projects related to (for example) PARI/GP, SageMath, Magma, OSCAR or the L-Functions and Modular Forms Database.

On the one hand, various topics where explicit computations have been the key for proving important results will be presented. These will be found in the context of modular forms, the study of rational points, as well as results towards the Birch and Swinnerton-Dyer conjecture. On the other hand, we will also focus on recently stated conjectures, for example the paramodular conjecture by Brumer and Kramer, and challenge participants to exhibit new examples to support such conjectures (in the case of the paramodular conjecture only one non trivial example is currently known).

We expect that the colloquium will lead to the emergence of new ideas and methods at the interface of these different fields, to new results as well as to new projects and collaborations.

This conference will be organized with the support of the National Research Agency in the framework of the project "MELODIA".

Description

ln this workshop, we will consider variants of Artin's primitive root conjecture leading to the study of the Galois groups of various radical extensions. Beyond the case of the multiplicative group studied by Lenstra and others, there are now also interesting results for elliptic radicals, and for division points in more general abelian varieties. ln this context, the elliptic analogue of Artin's conjecture is the Lang-Trotter conjecture, which is still open after more than 40 years.

The Galois representations associated to various division points in abelian varieties are central to understanding the Galois groups of the radical extensions that one tries to explicitly describe in this context, as they control the behaviour of the primes in the underlying problems. Understanding these Galois representations, and the entanglement between the extensions generated by different prime-power radicals, is essential to progress in this area.

ln this circle of problems and questions, one encounters interesting restrictions to local-global principles that will be addressed in this workshop, not only in the context of radical extensions.

Meeting Type: conference

Contact: see conference website

Description

A central topic in Diophantine Geometry is to understand how the geometry of a variety influences the arithmetic of its algebraic points, and conversely. Conjectures of Bombieri, Lang, and Vojta suggest that rational points of algebraic varieties satisfying suitable approximation conditions, are algebraically degenerate. On the other hand, conjectures on unlikely intersections suggest that algebraic points of special type —e.g. torsion points in semi-abelian varieties, special points in Shimura varieties— avoid subvarieties, unless the subvariety itself is also special (in a technical sense).

In recent years, a number of techniques have led to outstanding progress on Lang-Vojta conjectures, such as the Subspace Theorem, p-adic approaches to finiteness, and modular methods. Similarly, spectacular progress has been achieved on unlikely intersection conjectures thanks to new methods and tools, such as height formulas for special points, connections to model theory, refined counting results, and new theorems of Ax-Shanuel type (bi-algebraic geometry).

The goal of this workshop is to create the opportunity for these two groups to interact, to share their techniques, to update on the most recent progress, and to attack the outstanding open questions in the field.

The two directions described above are rather technical and specialized, and it seems necessary to bring together these groups of researchers to explain to each other not only the latest developments in their fields, but also the methods that made possible these breakthroughs. Thus, in this workshop we expect to have lectures explaining the main methods, as well as talks presenting the most recent progress in the subject by the world leading experts.

Description

The theme of the conference is a type of number theory that has become very popular over the last decades, and that is influenced by the possibility of « experimentally » studying arithmetic objects with the help of a computer. Thanks to the wide availability of computer algebra systems, essentially any number theorist nowadays has this possibility at his fingertips. There are concrete objects that are not so easily determined « by hand », such as fundamental units in number fields of higher degree, or Mordell-Weil generators of point groups of elliptic curves, and a first impression of « what these typically look like » is often obtained by numerical experimentation.

Over the years, substantial datasets relating to number fields, elliptic curves and L-series have become available, enhancing our understanding of the arithmetic world somewhat beyond only the smallest examples, which may fail to show the true asymptotic behaviour.

Meeting Type: workshop

Contact: Michael Stoll

Description

This workshop aims at bringing together the leading experts in the field, covering a broad spectrum reaching from the more theoretically-oriented over the explicit to the algorithmic aspects. The fundamental problem motivating the workshop asks for a description of the set of rational points X(Q) for a given algebraic variety X defined over Q. When X is a curve, the structure of this set is known, and the most interesting question is how to determine it explicitly for a given curve. When X is higher-dimensional, much less is known about the structure of X(Q), even when X is a surface. So here the open questions are much more basic for our understanding of the situation, and on the algorithmic side, the focus is on trying to decide if a given variety does have any rational point at all.

This is a workshop with about 50 participants. Participation is by invitation. Every participant is expected to contribute actively to the success of the event, by giving talks and/or by taking part in the discussions.

Description

During the 2023-24 academic year the School will have a special program on the p -adic arithmetic geometry, organized by Jacob Lurie and Bhargav Bhatt, who will be the Distinguished Visiting Professor.

The last decade has witnessed some remarkable foundational advances in p-adic arithmetic geometry (e.g., the creation of perfectoid geometry and the ensuing reorganization of p-adic Hodge theory). These advances have already led to breakthroughs in multiple different areas of mathematics (e.g., significant progress in the Langlands program and the resolution of multiple long-standing conjectures in commutative algebra), have uncovered new phenomena that merit further investigation (e.g., the discovery of new structures on algebraic K-theory, new period spaces in p-adic analytic geometry, and new bounds on torsion in singular cohomology), and have made hitherto inaccessible terrains more habitable (e.g., birational geometry in mixed characteristic). This special year intends to bring together a mix of people interested in various facets of the subject, with an eye towards sharing ideas and questions across fields.
