The purpose of this lecture series is to introduce the audience to basic ideas of specific areas of contemporary pure mathematics. Each lecture shall present an area: where it comes from, where it currently is, where it goes. Lectures will be given by prominent mathematicians twice a year: in the Spring and in the Autumn. Before and after each lecture we will organize reading seminars to prepare the audience for the lecture and to dig further into the topic of the lecture. With the lecturer’s consent, lectures will be recorded, slides and/or lecture notes will be provided if available.

Title: Abelianization in analysis of ODEs

Abstract: I will describe the exact WKB methodfor asymptotic analysis of families of ODEs in one variable, and itsinterpretation as a kind of abelianization procedure, which replacesGL(N)-connections over a Riemann surface by GL(1)-connections over an N-fold branchedcover. This abelianization procedure connects exact WKB to various subjects ingeometry (cluster algebras, moduli of Higgs bundles, enumerative geometry). Oneapplication is a conjectural description of Hitchin’s hyperkahler metric on themoduli of Higgs bundles; I will review some recent progress on theseconjectures.

Title: Abelianization in quantum topology

Abstract: I will describe new applications ofabelianization to various related subjects: perturbative Chern-Simonsinvariants, skein algebras, and conformal blocks. The aim is to explain howabelianization gives a unifying perspective on constructions familiar in eachof these subjects (e.g. dilogarithmic formulas for Chern-Simons invariants,vertex models for computing quantum invariants of links, and iterated-fusionconstructions of conformal blocks for the Virasoro algebra), and also suggestsvarious extensions, which are just beginning to be explored.

Founded in 1989, the Texas Geometry and Topology Conference (TGTC) has been held spring and fall ever since, a total of 67 times to date. The TGTC was conceived as a mechanism by which both the educational and the research atmosphere of the community of geometers and topologists could be enhanced. In order to accomplish this, the TGTC is organized so as to accomplish three specific goals:

(1) The TGTC is committed to bring researchers of national and international stature to Texas to discuss their research and to interact with mathematicians from Texas and surrounding states.

(2) The TGTC provides the community of geometers and topologists from Texas and surrounding states a convenient forum to meet and share mathematics on a regular basis. The geographic region is so large that few reasonable alternatives exist. The conference strongly encourages both individual research and productive cooperative efforts between schools.

(3) The TGTC is committed to the strengthening and enrichment of the mathematics personnel base. Graduate students, junior faculty, women, minorities, and persons with disabilities are especially encouraged to participate.

This Conference is supported by the National Science Foundation. Among the speakers of the current 68th edition of the conference are

Ian Anderson, Utah State University ; Robert Bryant, Duke University; Jarosław Buczyński, Institute of Mathematics of Polish Academy of Sciences (IMPAN); David Fisher, Rice University; Mikhail Gromov, Courant Institute of Mathematical Sciences at NYU and IHES, (to be confirmed); Shelly Harvey, Rice University; Dmitri Pavlov, Texas Tech University; Jinmin Wang, Chinese Academy of Science.

The information about all past Texas Geometr and Topology conferences can be found at ttps://www.math.tamu.edu/~tgtc/archive/

The conference will be held on the occasion of Professor Lusztig's retirement and will review progress in representation theory and related subjects.

The International Conference on Mathematics and Artificial Intelligence aims to provide a platform for researchers to present their recent works, share ideas and new methods in various fields of mathematics and artificial intelligence. It also provides an opportunity to improve collaboration between researchers from different countries who share similar research.

See the website for details on the subject matter of the workshop.

Per MFO rules, participation is generally limited to invited mathematicians. However, we have reserved a small number of places for early-career mathematicians, who may apply to participate by completing a short application.

Update: meanwhile this round of invitations has taken place, and the application form has been closed.

This workshop, sponsored by AIM and the NSF, will be devoted to interactions between p -adic geometry and chromatic homotopy theory. In particular, we will focus on the use of period maps and perfectoid methods to study the moduli stack of formal groups. We hope to use these methods to further our understanding of chromatic and transchromatic phenomena in stable homotopy and to see how the chromatic picture motivates and hints at possible novel results in p -adic geometry.

The main topics of the workshop are:

The p-adic geometry of the moduli stack of formal groups and its role in chromatic homotopy theory. Perfectoid methods in p-adic geometry. Period maps and generalized Rapoport--Zink spaces. This event will be run as an AIM-style workshop. Participants will be invited to suggest open problems and questions before the workshop begins, and these will be posted on the workshop website. These include specific problems on which there is hope of making some progress during the workshop, as well as more ambitious problems which may influence the future activity of the field. Lectures at the workshop will be focused on familiarizing the participants with the background material leading up to specific problems, and the schedule will include discussion and parallel working sessions.

Space and funding is available for a few more participants. If you would like to participate, please apply by filling out the on-line form no later than August 15, 2024. Applications are open to all, and we especially encourage women, underrepresented minorities, junior mathematicians, and researchers from primarily undergraduate institutions to apply.

Before submitting an application, please read the description of the AIM style of workshop.

A summer school and conference on the impact of recent developments in p-adic geometry on areas including the p-adic Langlands program, the p-adic Kudla program, and p-adic L-functions and Iwasawa theory

Knots in Washington 50 will take place from Friday, December 6 to Sunday, December 8, 2024 in Rome/Phillips Hall on the Foggy Bottom Campus at George Washington University. For those interested in attending the conference and/or giving a talk, please fill out the form on our website.

Plenary speakers include

• Keiko Kawamura (University of Iowa)

• Mikhail Khovanov (Johns Hopkins University, Baltimore, MD)

• Slava Krushkal (University of Virginia, Charlottesville, VA)

• Christine Lee (Texas State University, San Marcos, TX)

• Adam Sikora (University at Buffalo, Buffalo, NY)

The goal of the conference is to bring together international experts and young researchers working in foliations theory, diffeomorphism groups, 3-manifold topology, bounded cohomology, and 1-dimensional dynamics to share their insights and expertise and to foster collaborations that will lead to progress on important problems in both areas. Furthermore, to navigate the impact of the recent advances in each of these areas on the others, there will be minicourses to introduce young researchers to some of the major recent advances in these areas and there will be problem sessions and informal learning groups to come up with new problems within the scope of current techniques and long term projects between the subfields.

The research school is an introductory meeting to the thematic program “Representation Theory and Noncommutative Geometry” to be held at IHP from January to March 2025. The trimester is part of an ongoing effort to bridge two fiels of Mathematics : the representation theory of locally compact groups and the theory of operator algebras. These research domains share origins in harmonic analysis, spectral theory and quantum mechanics but grew in separate directions. Recent progress in representation theory, involving especially non-Riemannian symmetric spaces and spherical varieties, and new tools developed in operator algebras, especially those involving K-theory and the other methods of non-commutative geometry, offer exciting prospects for new work at the interface between the two fields.

Mini-course are:

• Erik P. van den Ban (Universiteit Utrecht): Harmonic analysis of non-Riemannian symmetric spaces
• Tyrone Crisp (University of Maine): Tempered representations from the point of view of Langlands, and from the point of view of operator algebras
• Omar Mohsen (Université de Paris-Saclay): Introduction to hypoelliptic operators and their index theory
• Hang Wang (East China Normal University): Groups C*-algebras and their K-theory

The purpose of the school is to present a self-contained proof of a famous theorem of Serre in 1972. This theorem tells us that the representation associated to the Galois action on the p-torsion points of an elliptic curve is surjective for p great enough. This theorem had a very great impact in the field of arithmetic geometry and opened the field to numerous problems that are, for some, still open today. After introducing the students to the topics needed to understand the proof, illustrating the theory through exercises and computer sessions, we will present the proof itself.

Intertwining operators are ubiquitous in representation theory. Their construction typically requires a considerable amount of analysis, and they often assume an interesting form. For instance, they are frequently pseudodifferential operators associated with pseudodifferential calculi of intense current study in noncommutative geometry. Conversely, in all multiplicity-one decompositions of representations (e.g. the theta correspondence), the essentially unique intertwining operator, or its symbol, should encode important information on the representation-theoretic decomposition.

However, those operators have received little attention from within operator algebra theory. This meeting will be the occasion to present classical and recent aspects of the theory of intertwining operators and explore the connections between operator algebras and representation theory.

Topics of special interest will include:

• Symmetry breaking operators: special families of intertwining operators between representations of a group and a subgroup. These operators, for Lie groups and algebraic groups over local fields, are the subject of intense study in various settings via analytic, algebraic and geometric methods.
• Concrete study of the intertwining operators appearing in the theta-correspondence over local fields, including interpretations coming from operator algebras and noncommutative geometry.
• Applications of intertwining operators in equivariant index theory and noncommutative geometry, such as K-theoretic constructions based on the BGG complex.

This Thematic Month aims to cover topics related to singularity theory of algebraic or analytic spaces, algebraic study of differential equations, and their applications to questions of transcendence. This 5-week program covers different themes that are often not closely related. One of the main objectives is to make them interact. To encourage participants (especially the youngest ones) to attend the entire month and foster interactions outside each one’s expertise zone, the scientific program of each week of the month will consist of courses accessible to non-experts, as well as more specialized presentations. This month will consist of five successive weeks: – Logarithmic and non-archimedean methods in Singularity Theory. The first week will focus on recent results based on methods in logarithmic geometry and non-archimedean geometry in singularity theory. – Foliations, birational geometry and applications. The second week will cover topics in birational geometry, including singularity resolution, MMP (Minimal Model Program), algebraic foliation theory, and local holomorphic dynamics. – Tame Geometry. The third week will address tame geometry in various forms: o-minimality, transseries, Hardy fields, non-archimedean analogs of tame geometry, and their applications to number theory. – Galois differential Theories and transcendence. The fourth week is devoted to differential Galois theory and its applications to questions of functional transcendence and number theory, as well as the study of periods and E and G-functions. – Enumerative combinatorics and effective aspects of differential equations. The last week is dedicated to enumerative combinatorics and certain effective aspects of differential equations, especially applications in enumerative combinatorics of techniques presented in the previous week, or as effective results on topics covered in the preceding weeks.

The workshop is aimed at algebraic and arithmetic geometers curious about the potential application of model theory in their research, as well as at model theorists who are keen to learn how their tools may be extended to answer questions of geometric interest.

The classification of tempered irreducible representations for real reductive groups was completed in the 1970s by Knapp and Zuckerman, following Harish-Chandra's work on the Plancherel formula. But some aspects of the subject are now undergoing a re-examination, following the discovery of new perspectives. C*-algebras and K-theory are valuable tools in Representation Theory, as shown, for instance, by the Mackey bijection. Indeed, it was the Connes-Kasparov isomorphism in K-theory that motivated the search for a natural bijection between the tempered dual of a real reductive group and the unitary dual of its Cartan motion group, as initially suggested by Mackey in the 1970s.

The meeting will focus on recent developments in which K-theoretic ideas have offered new perspectives on the tempered dual for reductive groups or symmetric spaces, and conversely on new approaches to operator-algebraic problems using contemporary tools in representation theory.

Topics will include:

• New approaches to the Mackey bijection through pseudodifferential operator theory, which has itself undergone an extensive conceptual redesign in the past decade, thanks again to C*-algebra and K-theory connections;
• New perspectives on the the Connes-Kasparov isomorphism using Dirac cohomology and cohomological induction;
• Higher orbital intergrals, which make it possible to go beyond the "noncommutative topology of the tempered dual'', hinting at something like the "differential geometry'' of this noncommutative space;
• Study of the Casselman-Schwartz algebras and their K-theory via Paley-Wiener theorems, and connections with the Connes-Kasparov isomorphism;
• C*-algebraic analysis of the tempered dual from the point of view of G as a symmetric space for GxG, and more generally of the tempered spectrum of symmetric spaces.

K-stability is a central topic in modern complex geometry. It characterises Fano manifolds that admit a Kähler-Einstein metric and provides a good notion of compact moduli space for Fano varieties. The winter school will bring together experts on K-stability who will give 3 mini-courses for PhD students and young researchers with a special focus on explicit problems in dimensions two and three. Along with lecture courses, there will be exercise sessions.

The speakers for the mini-courses are: Hamid Abban (University of Nottingham), Thibaut Delcroix (Université de Montpellier), Elena Denisova (University of Edinburgh), Ruadhaí Dervan (University of Glasgow), Kristin DeVleming (University of San Diego), Erroxe Etxabarri Alberdi (University of Warwick), Kento Fujita (Osaka University), Eveline Legendre (Université de Lyon).

This is a 4-day workshop that aims to explore connections between p-adic Arthur and ABV packets and geometric representation theory/the geometric Langlands program. It will feature talks from experts in both areas. The primary goal of this workshop is to foster new research directions and collaborations.

Harmonic analysis on homogeneous spaces is a fundamental area of research that simultaneously generalizes classical harmonic analysis on groups and on Riemannian symmetric spaces. It naturally relates to many areas of mathematics, playing a central role in representation theory and the theory of automorphic forms.

This workshop will be an occasion to introduce recent developments in some of these areas. It will also aim to explore new connections between them and extend the fruitful interactions between C*-algebras, harmonic analysis and representation theory beyond the classical setting of groups to the general setting of homogeneous spaces.

Topics will include:

• C*-algebraic approaches to the tempered dual of non-Riemannian symmetric spaces;
• Harmonic analysis and Plancherel theory for spherical spaces;
• Connections with the Langlands program and periods of automorphic forms;
• Recent approaches to the theta correspondence via C*-algebras

Building on the success of the four previous conferences (held in 2017, 2019, 2021 and 2023) this biennial event will aim to draw together the considerable community of researchers and practitioners who use and / or develop innovative mathematics and data driven approaches, relevant to the applications and theory of Operational Research (OR). The conference will be held at the beautiful and easily accessible Conference Centre Aston in Birmingham and will showcase activities from across all areas of OR. We welcome contributions that are empirically motivated and with a focus on application, as well as those that are theoretically driven. The conference will host plenaries from leading international experts, sessions of themed talks, as well as poster sessions, and will provide plenty of opportunities for networking. We look forward to seeing you in Birmingham in April 2025 for a terrific event and to celebrate together the successes of OR! EDI The IMA, the OR Society, and the conference committee strongly support diversity and inclusion. It is our intention to host a conference that is welcoming and inclusive for all, and we will be making active efforts to support the participation of individuals and groups who are under-represented at such academic events and in our discipline more broadly. As part of improving understanding amongst the OR community of the different barriers individuals face, we would like to invite session leaders and individual speakers to include as part of their presentation(s) their own experiences of achievement, inclusion, and exclusion. This will be complemented with a number of focused sessions with key speakers on the particular challenges faced by different groups.

The conference "Number Theory, Quantum Chaos and their Interfaces” aims at gathering distinguished researchers working in either of the disciplines to discuss recent research advances in these fields, and serve as a playground for the exchange of ideas between these, rather diverse, research communities. Another purpose of our conference is to provide a solid educational platform for more junior researchers who aspire to conduct research in the relevant fields and expose them to some of the outstanding results and open problems.

This meeting will take place on the occasion of the 60th birthday of Francesco Pappalardi. This event honours his outstanding contributions to number theory, and will also be a recognition of his exceptional activity in promoting mathematics in countries which need it the most. In particular, Francesco is a driving force for mathematical cooperation between Kurdistan Iraq and other countries, including Italy. This conference will be an opportunity to feature outstanding international mathematicians in Erbil and showcase the scientific potential of Kurdistan Iraq.

This is the 37th annual Shanks Conference, focusing on all aspects of constructive function theory and related areas, including orthogonal polynomials, special functions, potential theory, energy optimization, and various problems related to optimization and efficiency.

This is a graduate student workshop on discrete groups in topology and algebraic geometry. This includes topics like fundamental groups of varieties and mapping class groups. This is the second week of a three week long thematic program. The conference the following week may also be of interest to graduate students.

This is a conference on discrete groups in topology and algebraic geometry, which includes topics like fundamental groups of varieties and mapping class groups. This is the third week of a thematic program on the topic.

In recent years, there has been an explosion of activity surrounding algebraic points on curves, from many different perspectives. These include the study of measures of irrationality, isolated and parametrized points, computational methods to determine algebraic points, and the arithmetic statistics of algebraic points. In this workshop, we aim to bring together researchers from these diverse perspectives, with the particular goal of developing bridges between them. The workshop will include overview talks on the various perspectives, research talks, an open problem session, and structured time for collaboration.

Flows involving solid particulates are ubiquitous in nature and industry alike. Such flows are found in pharmaceutical production, the chemical industry, the food and agricultural industries, energy production and the environment. Many unsolved problems remain, however. In order to be able to solve problems, granular flows need to be understood so that their behaviour can be controlled and predicted. We are able to describe rapid granular flows, where the particles are highly agitated and there has been some success describing static systems. The intermediate regime, where these two phases meet and coexist, is not as well understood and yet is the most commonly observed behaviour of granular flow. The objective of this meeting will be to interface the two ends of the particulate flow spectrum – those working to understand the fundamentals of granular flows and those attempting to control particulate flows in an industrial setting – to develop solutions to the complex problems presented by dense granular flows. Themes will include dense granular flow, biological systems, self-propelled particles and geological flows, exploring new developments in theoretical analysis and experimental techniques. All attendees will be provided with an opportunity to present recent work and there will be substantial time for discussion, both during the workshop and during the evening! Postgraduate and PhD students are particularly welcomed and oral presentations will reflect the breadth of the field.

The 1st IMA Mathematics Anxiety International Conference will take place at the Centre for Mathematical Sciences, the University of Cambridge, in the heart of the historical city. It aims to bring together researchers, academics, teachers, publishers, policy makers and all interested in the conference theme from all over the world.

During this one week summer school, Eleonora di Nezza (Paris, Sorbonne) and Siarhei Finski (Paris, CNRS) will give introductory talks on Kahler geometry to a group of non-experts, primarily composed of students and postdocs. Registration to open soon. The event is part of a special semester on complex geometry at the Renyi Insitute.

Eleonora Di Nezza: Pluripotential theory and L∞ estimates for complex Monge-Ampère equations

Abstract: In these lectures, we introduce and explore fundamental concepts in pluripotential theory, which are essential for studying (degenerate) complex Monge-Ampère equations on Kähler manifolds. We then shift our focus to a novel approach for obtaining L∞ a priori estimates for these equations. This method, which has a "local" character and relies solely on the use of envelopes, was recently developed by Guedj and Lu.

Siarhei Finski: Asymptotic study of submultiplicative filtrations

Abstract: It has long been recognized that the study of manifold degenerations plays a crucial role in addressing many questions in geometry, including the search for canonical metrics. Some degenerations can be understood on the algebraic level through the so-called submultiplicative filtrations, which are certain filtrations on rings respecting the algebraic structure. The most basic example is the filtration on the space of homogeneous polynomials given by the order of vanishing along a subvariety in the projective space.

This course is about the geometric quantization approach to these filtrations, which effectively establishes several results at the crossroads of algebraic and differential geometry. We discuss some applications towards the search of canonical metrics and cover the necessary preliminaries including the Ohsawa-Takegoshi extension theorem, Bergman kernels, and the theory of graded normed algebras.

During this one week summer school, Hans-Joachim Hein (Munster) and Daniele Angella (Firenze) will give series of talks on recent advances on Singular Kahler metrics, and Hermitian geometry respectively. We expect that the audience will consist of advanced graduate students, postdocs and junior faculty working in complex geometry. Both speakers will deliver 4 lectures of 50 minutes, with each lecture accompanied by a problem session. Registration to open soon. This event is part of a special semester on complex geometry at the Renyi Insitute

Daniele Angella: Cohomological properties and Hermitian metrics of complex non-Kähler manifolds

Abstract: the first lectures will provide a survey of the cohomological properties and topological aspects of complex manifolds, as well as canonical metrics on complex manifolds. We will then focus on some analytic problems concerning the geometry of the Chern connection on Hermitian manifolds, such as the existence of metrics with constant Chern-scalar curvature, generalizations of the Kähler-Einstein condition to the non-Kähler setting, the convergence of the Chern-Ricci flow on compact complex surfaces, and the asymptotic behavior of Monge-Ampère volumes of Hermitian metrics in the ddc-class.

The René 25 conference's purpose is to celebrate the research interests of René Schoof.

Part of a series of conferences: NTDU

During the 2025-26 academic year the School will have a special program on Arithmetic Geometry, Hodge Theory, and O-minimality. Jacob Tsimerman, University of Toronto will be the Distinguished Visiting Professor.

The purpose of this special year will focus on recent developments in hodge theory and o-minimality and their applications to arithmetic geometry. There has been much progress over the last 15 years in using transcendental uniformization maps to study arithmetic questions (general shafarevich theorems, results on unlikely intersections, general bounds on rational point counts). It has become increasingly clear that hodge theory (both classical and P-adic) and the resulting period maps form a natural home for these kinds of investigations to arise. In the other direction, O-minimality has been applied with success to make progress on questions in Hodge theory (Griffiths conjecture, definable period maps), and has recently had its own explosion of results (sharply O-minimal sets, the resolution of Wilkie's conjecture).

The goal of this year will be to bring together researchers in these different fields, with the aim of extending the collaboration between areas, share key insights, and investigate how far existing methods can be pushed.

Senior participants: Gal Binaymini, Ben Bakker (to be confirmed), Jonathan Pila and Claire Voisin (STV)

The aim of this workshop is to explore recent advances in Kähler geometry, focusing on non-Archimedean aspects of the Strominger--Yau--Zaslow conjecture, potential-theoretic approaches to singular Kähler-Einstein metrics, geometric estimates for solutions to Complex Monge–Ampère equations, connections with the minimal model program, and Calabi-Yau metrics on non-compact manifolds.
