Jean-Morlet Chair whole semester on Numerical Methods for PDEs: Discretization, Iterative Solution & Parallelization (Martin Gander and Florence Hubert)
01 jul 2022 - 31 dec 2022 • CIRM Luminy, Marseille, France
Résumé:
Only in very rare cases, and on very specific domains, is it possible to give closed form solutions for PDE equations, and a large part of research in numerical analysis is devoted therefore to computing approximate solutions. This requires several steps: firstly, one needs to discretize the PDEs. A first focus of our proposal is to look at a very sophisticated, new type of discretization of finite volume type: the discrete duality finite volume (DDFV) method. We will also focus on domain decomposition methods where there exist many open research questions on which the community is currently focusing: (coarse spaces, heterogeneous domain decomposition methods, domain decomposition for optimal control problems, PinT methods, etc.) Our program will feature the international PinT Conference, a research school for PhD students, workshops and research in pairs and a doctoral course. Invitations are open to tentative participants at all levels of their career.

Morphisms in Low Dimensions
11 jan 2023 - 28 jan 2023 • Oberwolfach, Allemagne
Organisateur:
Mathematisches Forschungsinstitut Oberwolfach (MFO, Oberwolfach Research Institute for Mathematics)
Résumé:
Watanabe's work on embedding calculus has shown us how diffeomorphisms of the 4-sphere may be studied, and Zemke's work has used the functoriality of Floer homology to derive powerful new obstructions to ribbon concordance. A common theme in these works is the emphasis on functoriality of the invariants, rather than simply computation, and a renewed interest in understanding diffeomorphism groups of a manifold rather than single isotopy groups. In this workshop, we propose to bring together experts on these interrelated topics with the aim of improving community understanding of recent developments in low-dimensional topology and promote new advances in the study of global properties of 4-manifolds.

COUNT — Computations and their Uses in Number Theory
27 fév 2023 - 03 mar 2023 • Luminy, France
Organisateur:
Centre International de Rencontres Mathématiques
Résumé:
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.

BIRS Workshop — Perspectives on Matrix Computations: Theoretical Computer Science Meets Numerical Analysis
05 mar 2023 - 10 mar 2023 • Banff, Alberta, Canada
Organisateur:
Banff International Research Station (BIRS) for Mathematical Innovation and Discovery
Résumé:
Computations with matrices, such as their multiplication, are fundamental operations that are executed on millions of devices, from smartphones to supercomputers, every day. But what is the minimum number of operations it takes to multiply two matrices? Surprisingly, the answer is currently unknown. The problem of determining the complexity, or the number of operations required to perform a certain computation, goes back to the very origins of computing. In the age of large-scale scientific computing, big data, and machine learning, understanding the complexity of computations is crucial for designing algorithms that are efficient in terms of both time and energy. There are two distinct research communities in computer science and mathematics working to answer these questions. Each community brings different perspectives and different approaches, but they rarely interact with each other to the detriment of both. To truly advance the state-of-the-art and tackle huge computational problems, cooperation and collaboration is needed. This workshop will bring together a diverse group of researchers in theoretical computer science and numerical analysis to shape the future of research on the complexity of matrix computations.

Trends in Computational Discrete Optimization
24 avr 2023 - 28 avr 2023 • ICERM / Brown University, Providence, Rhode Island, États-Unis
Organisateur:
ICERM / Brown University
Résumé:
The aim of this workshop is to discuss many exciting recent developments on the computational side of discrete optimization. The workshop has three main themes. The first theme is that of commercial and academic/open-source solvers that have allowed the solution of very large-scale problems, and of recent developments in exact solvers that have allowed for proofs of results in logic, knot theory, and combinatorics. The second theme is the interaction between optimization and machine learning: these two areas complement each other in several ways. The third theme is quantum computing and unconventional computing architectures: quantum computing has been used to tackle combinatorial optimization problems, and quantum algorithms exist for other related optimization problems such as linear and semidefinite relaxations.

FoCM 2023 — Foundations of Computational Mathematics 2023
12 jui 2023 - 21 jui 2023 • Paris, France
Organisateur:
Sorbonne Université
Résumé:
The conference in Paris will be the ninth conference of the Society, following the meeting that gave birth to the idea of FoCM in Park City (1995), and 8 very successful meetings in Rio de Janeiro (1997), Oxford (1999), Minneapolis (2002), Santander (2005), Hong Kong (2008), Budapest (2011), Montevideo (2014) and Barcelona (2017). The conference in Vancouver planned for 2020 was cancelled due to the Covid-19 pandemic. Each of the previous conferences had several hundred participants from all branches of mathematics that impinge on computation in the broadest sense. FoCM conferences are usually organized as follows: mornings are devoted to plenary talks and afternoons to the workshops, which are run in parallel. The conference is divided in three periods of three days, and each workshop is held during one of these periods. The spirit of FoCM is that participants are encouraged to come to the whole duration of the conference, and attend talks in different workshops. Poster sessions are also organized by each workshop.

Data Science and Social Justice: Networks, Policy, and Education (Part II)
20 jui 2023 - 28 jul 2023 • Providence, Rhode Island, États-Unis
Organisateur:
ICERM
Résumé:
In Summer 2023, ICERM hosts the second of two summer programs entitled The Social Justice and Data Science Summer Research Program. This program aims to increase interest, research training, and capacity for data science for social justice, and to develop both quantitative and qualitative approaches to those professional practices that call for community engagement, critical inquiry, and interdisciplinary cooperation. Building off of Summer 2022's program, which included a workshop on network science and analysis as well as foundational conversations with community partners, the Summer 2023 program will advance the mathematics community's understanding of the complexity of computational social justice work through three emphasis areas (1) policy, (2) education, and (3) community-driven research. As a new field emerges at the face of computational and applied mathematics and social justice, this requires new methods for working across community lines. In order to address the novel and interdisciplinary problems arising out of community needs, participants will work together to develop new or refine existing computational methods whose applications may be broader than the original problem. The organizers are committed to working with humility and in solidarity with one another and with the local community. The program will include engagement with the local community and invest in the education of the next generation of researchers by driving the development and direction of new computational methods for quantitative social justice research. Researchers with expertise and interests in using mathematical models and/or data science to examine social justice issues in policy and/or education are particularly encouraged to apply. The organizers also seek applications from researchers with specialties in digital humanities, computational social science, and data science education.

Workshop — Recursion Theory and its Applications
15 oct 2023 - 20 oct 2023 • Hangzhou, Chine
Organisateur:
Institute for Advanced Study in Mathematics (IASM) in Hangzhou, China
Résumé:
Recursion theory measures the complexity of mathematical objects in terms of what is computable, in other words, what can be determined by a computer with no space or time limitations. We can define, for example, computable sets of natural numbers, computable (continuous) functions on the real numbers, or computably enumerable open subsets of the reals. Adding an oracle---an outside source of information---allows us to extend the reach of recursion theory beyond the computable. For example, every continuous function on the real numbers is a computable function relative to some oracle. For another example, a set of real numbers has Hausdorff dimension zero if and only if there is an oracle relative to which every real in the set can be significantly compressed. In this way, recursion theory offers a fine-grained way to analyze some of the most central notions in mathematics. This has recently led to deep applications to analysis, number theory, and set theory. The focus of this workshop is on understanding and extending these applications of recursion theory.
