There has been an enormous amount of progress in the analytic theory of zeta and L-functions over the past decade. Our understanding in the classical theory of the value distribution of the Riemann zeta function has achieved new heights with spectacular breakthroughs on moments and extreme values (both local and global) leading to a better understanding of families of L-functions more generally. Great strides have also been made for higher degree L-functions through the remarkable achievements in subconvexity problems and higher degree trace formulae.

These techniques are still in their infancy and there is great scope for exploration and new applications. The aim of this conference is to bring together distinguished researchers working in the classical analytic, probabilistic, and automorphic theories and utilise the creative environment of MPIM and Bonn to further develop these important interactions.

This is a workshop where the participants will write computer code corresponding to mathematical results needed in the proofs of the main theorems of local and global class field theory. The participants should have some basic knowledge of at least one of, and ideally both of, the number theory involved in the proofs, and the Lean theorem prover.

The 2025 Progress in Discrete and Continuous Probability Conference will take place Tuesday, July 22 — Friday, July 25, 2025, on the historic campus of Union College in Schenectady, NY. The aim of the conference is to bring together researchers at all career stages in a welcoming environment to learn and present recent advances in both discrete and continuous probability, benefiting especially from the interaction between the two.

The following plenary speakers will give mini-courses over the first three days of the conference: Omer Angel (University of British Columbia) and Yimin Xiao (Michigan State University). There will also be several invited and contributed talks.

The conference has received NSF funding to support the travel costs of early career individuals (graduate students/postdocs/assistant professors, as funding allows). Deadline to register in order to be considered for funding is May 19th, 2025. Among the conference activities is a lunch panel on navigating early career stages.

QTMART is a workshop on algebra and representation theory taken in a broad sense, run by and for queer and trans mathematicians. It aims to showcase the research done in this field by this community and bring together senior researchers, junior researchers, and graduate students to discuss topics of common interest in a non-competitive environment.

Alongside the workshop, an exploratory program on queer mathematics and inclusion will take place. The activities of the program will focus on exploring what it means to do mathematics as a queer or trans mathematician, and if there is such a thing as queer mathematics. It will also address the question of how to make the working culture and environment more welcoming and diverse, and will aim to initiate concrete actions in this regard.

This workshop welcomes talks by early-career researchers. Please indicate on the application form if you would like to give a talk and on what topic.

The event is open to everyone accepting the community agreement (which will be based upon Oberwolfach's Statement of Respect and Collegiality https://www.mfo.de/about-the-institute/guiding-principles/equality-diversity-inclusion/statement-for-respect-and-collegiality, taking suggestions from the participants into account). However, priority in assigning talks will be given to self-identifying queer and trans mathematicians, and some activities in the program will be reserved for this group.

Plenary Speakers:

• Chris Bowman (University of York)
• Ian Musson (University of Wisconsin-Milwaukee)
• J. Daisie Rock (FWO, KU Leuven, UGent)
• Beth Romano (King's College London)
• Dani Tubbenhauer (University of Sydney)

This conference aims to bring together early career researchers in geometric group theory, arithmetic geometry and analysis of PDEs, who will also have the opportunity to present their own results.

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.

We are hosting two events, each one a week long:

• A summer school on Galois Representations, Relative Langlands Duality, Beyond Endoscopy, and Relative Trace Formulae. 4-9 August 2025.
• A number theory conference. 11-15 August 2025.

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.

Mini-Courses by Dima Arinkin and Linus Hamann.

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.

The year 2024 will mark the 30th anniversary of the resolution of Fermat’s Last Theorem, one of the most celebrated applications of the Langlands program. In the three decades since, many seemingly disparate areas of research within the Langlands program have blossomed, some inspired by the ideas introduced in the proof of Fermat, some with a more geometric flavor, made possible in part by the theory of perfectoid spaces, and some with a more representation-theoretic flavor.

The categorical Langlands program is an emerging conceptual framework that encompasses these disparate areas of research: the $p$-adic Langlands program, the geometrization of the local Langlands correspondence, and the cohomology of Shimura varieties in its many incarnations, just to name a few. This workshop brings together architects of the categorical Langlands program in the number field setting as well as emerging experts. The goals are to take stock of the state of the art in the field, and to chart a course for future developments, and to provide mentorship and support to a diverse group of early-career participants.

Due to limited space, in-person attendance at this meeting is by invitation only. However, we welcome applications for virtual participation in the workshop. If you are interested in virtual attendance, please apply at the following link: https://forms.gle/kPz15Cnj8CGKKkJy9.

Description: Classical PDEs involve partial derivatives of a function of multiple variables describing physical quantities. These are crucial for understanding continuous processes across disciplines, with solutions often forming the basis for applied research and technological developments. Fractional PDEs are an extension of classical PDEs, which generalize derivatives to non-integer orders. These equations have become a valuable tool for modelling complex, real-world systems exhibiting features not adequately captured by traditional PDEs.

Spectral methods are known for their exceptional accuracy and efficiency in solving a wide range of differential equations with flexibility in handling various types of boundary conditions. These methods exhibit exponential convergence rates and are suitable for numerical simulations requiring precise solutions. These methods offer flexibility in choosing basis functions tailored to specific problem characteristics. Their ability to resolve high-frequency components and global nature makes them indispensable tools in scientific computing and engineering simulations, where precision and computational efficiency are paramount.

The class of methods and problems which cover the theme of the symposium are listed:

Class of Spectral Methods: Collocation Methods, Galerkin Methods, Tau Methods, Sparse Grid Methods, Pseudo Methods, Multidomain Methods, Finite Difference / Finite Volume Methods, Hermite and Laguerre Spectral Methods, Radial Basis Function Spectral Methods, Hybrid Spectral Methods and much more…

Class of Problems: Fluid Dynamics, Quantum Mechanics, Electromagnetics, Structural Mechanics, Meteorology, Climate Modeling, Parametrized PDEs, Time-dependent PDEs, Stochastic PDEs, Complex PDEs, Singular PDEs, Turbulence Modeling, Image Processing, Elasticity, Geophysics, Nonlinear Wave Equation Solitons, Pattern Formation, Travelling Waves, Mathematical Physics, Biological Models, Epidemiological Models, and much more fractional PDEs …

Publications: Extended abstracts will be published in Special Volume of the American Institute of Physics Conference Proceedings. For details, please refer to the link: Papers–ICNAAM 2025.

Also, the papers can be considered for a special issue of the journal Fractal and Fractional. For details, please refer to the link: Special Issue: Fractional Equations and Applications.

This workshop, sponsored by AIM and the NSF, will bring together experts in mathematical modeling, biomedical engineering, and clinical research to advance multiscale modeling approaches that bridge ocular, cardiovascular, and systemic dynamics. The non-invasive nature of ocular measurements, such as retinal blood flow and intraocular pressure, provides a unique opportunity for early diagnosis and monitoring of conditions such as diabetes, hypertension, heart failure, and neurological disorders. However, translating these insights into clinical practice requires a strong collaboration between clinicians and modelers to design interpretable and actionable approaches. A key focus of the workshop will be integrating mechanistic models with data-driven approaches, balancing interpretability with predictive power.

The workshop focuses on the interplay between 3-manifold topology and geometry, the study of 3-manifold groups, and character and representation varieties, with connections to computational topology and theoretical computer science. Related topics are also welcome! This two-day event will feature introductory lectures, in-depth research talks, lightning talks, and dedicated discussion sessions. Our goal is to foster a stimulating environment by bringing together participants at various career stages, along with many local researchers.

This workshop, sponsored by AIM and the NSF, will be devoted to further developing the method of flag algebras and its applications. Flag algebras, developed by Razborov in 2007, allows one to solve problems in combinatorics via streamlined calculations that combine elements from computer engineering and optimization. It led to many recent breakthroughs on long-standing open problems of Erdős, Sós, Turán, Gromov and Zarankiewicz, to name a few. The technique is versatile and can be applied in other settings than graphs and hypergraphs including permutations, oriented graphs, point sets, embedded graphs, and phylogenetic trees.

Mathematics is at the heart of evidence-based decision support; however, any decision requires data collection, data and signal processing, communications and communication systems to reduce cognitive burden for the decision maker and improve decision making. It is also increasingly common for AI to play a role in summation and processing, meaning that evidence is even more varied in its utility and applicability. This conference will explore both the state of the art in terms of data curation, signal processing, communication and AI to support decision making as well as looking at the impact of these systems on cognitive load. Importantly this conference will focus on research that can start to explore the confluence of these areas in order to underpin decision making in a rigorous and integrated system. As mathematics begins to underpin more of the decision-making process, so it becomes more important that that mathematics is integrated and focussed on providing understandable evidence to the decision maker. Therefore, how the mathematical evidence is then communicated becomes as important as how the mathematics is undertaken. The conference will aim to bring together a wide variety of participants applying a variety of mathematical methods with defence and security applications. The programme will include invited speakers, presentations and poster sessions, as well as refreshment breaks for informal discussions. It is aimed towards a cross-discipline audience of mathematicians, scientists, engineers and communicators from both industry and academia, in addition to government and military personnel who have an interest in how mathematics can be applied to defence and security problems. The scope of the conference includes but is not limited to the following topics: 1. Mathematics for Decision Support • Decision Support Systems for Defence • Data mining and Statistical Learning • Multi-objective and Multi-criteria Optimization • Data Fusion Systems in Defence Applications 2. Signal Processing and Communications • Multimodal Signal Processing • Distributed Signal Processing • Integrated Communications and Sensing Systems • Sensor Management for Defence Applications 3. Artificial Intelligence and Machine Learning • Machine Learning for Defence Applications • Cognitive Systems to support Decision Making • Data Collection and Curation for Defence Call for Abstracts Abstracts will be considered for the conference based on a 300 word abstract for oral presentation. Abstracts should be submitted by 23rd May 2025 via https://my.ima.org.uk/

This 2-day special session will be dedicated to a range of mathematical problems related to motion planning algorithms and their properties. A central role is played by the notion of topological complexity (TC), which is a homotopy invariant depending only on the configuration space of the robot that can be studied using diverse tools from a variety of fields, such as geometry, topology, algebra, combinatorics, etc. This session on theoretical and applied aspects of TC and related sectional category invariants aims to bring together scientists from all over the world working on different aspects of motion planning and TC and foster collaboration among them, expose graduate students and junior colleagues to these rich and fascinating areas of research, and identify directions for future work and interaction in these areas.

This workshop, sponsored by AIM and the NSF, will be devoted to recent advances in computing the stable homotopy groups of spheres. The last 10 years have seen significant progress in this area, driven first by applications of motivic homotopy theory and then more recently by the invention of synthetic/filtered spectra, which generalizes motivic techniques. Last year, Weinan Lin, Guozhen Wang, and Zhouli Xu significantly extended the known range of stable homotopy groups and used these computations to resolve the remaining case of the Kervaire Invariant One problem, which has remained open for about 60 years. This workshop will focus on the advances that made these computations possible, especially those involving machine computations and synthetic techniques, and look for applications of these new techniques, for example to the equivariant slice spectral sequence.

Topological Data Analysis (TDA) is a research area at the intersection of Algebra, Topology, Geometry, Statistics and Machine Learning. While methods from TDA have been applied successfully to data from a variety of domains — from financial mathematics, to materials science, climate science, biomedical imaging, or social science —, there has been less work done on studying in a principled way how such methods can be applied to data that changes dynamically over time. The goal of this workshop is to bring together experts in TDA with experts in application domains in which time-varying data is particularly prevalent. Examples include time series in climate modelling and financial mathematics, as well as dynamic networks in epidemiology and social science modelling.

IEEE VIS Workshop on Topological Data Analysis and Visualization (TopoInVis 2025) Co-located with IEEE VIS 2025 - Vienna, Austria, 2-7 November

Call for Contributions

Topological methods have become an established framework for the extraction and analysis of structural patterns in complex data. It has been successfully applied in a variety of application fields, including quantum chemistry, astrophysics, fluid dynamics, combustion, material sciences, biology, and data science. In particular, the genericity, efficiency, and robustness of topological methods have made them particularly well suited for the multi-scale, interactive analysis and visualization of the underlying structural information of data.

Despite their rising mainstream popularity, topological methods still face a number of challenges, including, for instance, efficient computational methods for large-scale time-varying data, the characterization of noise and uncertainty, or the support of emerging data types, such as ensemble data or high-dimensional point clouds.

The IEEE VIS Workshop on Topological Data Analysis and Visualization aims to be an inclusive forum for the fast dissemination of the latest results in theory, algorithms, and applications of topological methods for the interactive and visual analysis of data. This workshop is open to members of the visualization community interested in topological methods and to experts in topological methods from other communities willing to experiment with interactive and visual applications.

The workshop welcomes submissions of both full-length papers and posters. The accepted papers will be presented during the workshop, and the accepted posters will be presented at the main poster event at VIS and give a lightning talk during the workshop.

Scope

Relevant topics include (but are not limited to): Topological methods for the analysis and visualization of all types of data, including but not limited to: Graph data Scalar, vector, tensor, multi-field data Time-series data High dimensional point cloud data Ensemble data Data with uncertainty Topological methods for data science (dimensionality reduction, clustering, etc.) Topological methods and machine learning Computational methods for topological data analysis and visualization Software systems for topological data analysis and visualization Visual analytic frameworks relying on topological methods Applications of topological data analysis and visualization

This workshop, sponsored by AIM and the NSF, will be devoted to studying arithmetic dynamics of multiple maps. In classical arithmetic dynamics, we consider the iteration of a single endomorphism of a variety defined over a field of arithmetic interest — typically a number field or the function field of a curve. An exciting new direction in arithmetic dynamics that holds particular promise for striking new results is what we call "dynamics of multiple maps": dynamical behavior arising from the interaction of two or more endomorphisms on the same space.

This workshop, sponsored by AIM and the NSF, will be devoted to non-Archimedean methods in complex geometry. The main topics for the workshop are: K-stability and canonical metrics, Degenerations of Calabi–Yau manifolds and the SYZ Conjecture, and Algebro-geometric and tropical aspects of degenerations.

The annual New Zealand Mathematics Conference will take place in Hamilton, the heart of the north island of New Zealand. This is a general mathematics conference - particpants from all branches of mathematics are welcome.

moments of the derivative of characteristic polynomials of matrices from the classical compact groups, and of the analogous L-functions.

These inquiries become particularly intricate when the exponent on the derivative is non-integer or when the evaluation point of the characteristic polynomial approaches the unit circle at varying rates. Exploring these statistics will improve our understanding of the distribution of zeros, and the value distribution of L-functions

This workshop, sponsored by AIM and the NSF, will bring together researchers from across the mathematical sciences to apply a broad range of mathematical, statistical, and data science tools to study the mathematical sciences community. The workshop will include both researchers currently working in this area, as well as researchers new to the field interested in applying their expertise to this area.

This workshop, sponsored by AIM, the NSF, the Topos Institute, and the US NSF Center for Analysis and Prediction of Pandemic Expansion, will consider how category-theoretic foundations for modeling as decision support for multidisciplinary collaboration might advance insights into pandemic science. Multidisciplinary modeling is extremely useful and also extremely difficult (for many reasons). By taking the very concept of "building a model" as itself a sort of model, and phrasing this in the formal mathematical language of (double) category theory, we can develop systems that greatly improve our capabilities for collaborative modeling.

The workshop will bring together a wide range of research communities: category theory, software engineering, dynamical systems, data science, epidemiology, infectious disease modeling, medical geography, behavioral psychology, social and urban networks, and economics.

Thematic Month on the Langlands program

This workshop, sponsored by AIM and the NSF, will be devoted to new developments in integral p-adic cohomology theories, focusing in particular on their applications to the study of integral models of Shimura varieties. The main topics for the workshop are (1) Prismatic/syntomic realizations for Shimura varieties beyond hyperspecial level. (2) Characterizing and constructing integral models of local and global Shimura varieties. (3) Applications to automorphic forms and cohomology of Shimura varieties
