The conference « Reductive groups and automorphic forms » marks the closing of the European Research Council project « Arithmetic of automorphic motives, » (AAMOT) and it is dedicated to the French school of automorphic forms and to the colleagues who have contributed to its vitality over many decades. We find it especially appropriate to dedicate the conference to the memory of Roger Godement, who passed away on July 21, 2016, and whose early and consistent commitment was of such importance in establishing Paris as a major international center in the Langlands program and in the theory of automorphic forms more broadly understood.

Combinatorics an Arithmetic for Physics: special days

The meeting’s focus is on questions of discrete mathematics and number theory with an emphasis on computability. Problems are drawn mainly from theoretical physics (renormalisation, combinatorial physics, geometry) or related to its models. Computation, based on combinatorial structures (graphs, trees, words, automata, semirings, bases) or classic structures (operators, Hopf algebras, evolution equations, special functions, categories) are good candidates for computer-based implantation and experimentation.

As part of the European Research Council Starting Grant programme « Quantum Algebraic Structures in Field Theories » (QUASIFT) activities, this conference aims to unite physicists and mathematicians working on non-local aspects and higher structures in quantum field theories.  Through lectures and informal discussion we will further the productive dialogue between experts studying the application of physical concepts in algebraic geometry and homotopy theory, and the appearance of novel algebraic structures in theoretical physics.

Topics of discussion will include structures associated to line and surface operators, boundary conditions and defects, moduli spaces of vacua, the cobordism hypothesis, factorization homology, and the occurrence of E_n, P_n, chiral and other higher structured algebras.

The 2021 IHES Summer school on « Enumerative Geometry, Physics and Representation Theory » will be held in a blended format at the Institut des Hautes Etudes Scientifiques (IHES) from 5 to 16 July 2021 with a reduced number of selected participants and through Zoom for all those who are interested in the subject (cf.link to the new registration form below).

This school is open to everybody but intended primarily for young participants, including Ph.D. students and postdoctoral fellows.

The School will be managed via a Slack workspace. If you have registered but you have not received yet the registration link to the Slack workspace, please contact Francesco Sala

The main theme of this Summer School is enumerative geometry, with particular emphasis on connections with mathematical physics and representation theory. As its core, enumerative geometry is about counting geometric objects. The subject has a history of more than 2 000 years and has enjoyed many wonderful breakthroughs in the golden years of classical algebraic geometry, but we will be interested in more recent developments.

This Summer School will focus on the following main subjects:

counting curves and sheaves (Gromov-Witten theory, Donaldson-Thomas and related theories)
gauge theory enumerative geometry (3d gauge theories and Coulomb branches, 4d gauge theories, and Vafa-Witten invariants, etc)
applications of enumerative geometry to categorification and low-dimensional topology
Hall algebras and their refined versions (cohomological, K-theoretic, derived categories)

The IHES 2020 Summer School on « Motivic, Equivariant and Non-commutative Homotopy Theory » will be held from 6 to 17 July 2020.

This school is open to everybody but intended primarily for young participants, including PhD students and postdoctoral fellows.

The IHES 2020 Summer School will focus on topics in motivic and equivariant homotopy theory, and non-commutative geometry.

These three subjects are currently experiencing a phase of intense growth and development:

long-standing central conjectures have been solved;
existing theories are being perfected;
many new foundational developments are being made on this basis.

It’s expected that these developments will spur many further advances and interactions in the near future.

The lecture series and research talks at the IHES Summer School will focus on presenting the latest developments in topics related to categories of motives, calculational and foundational aspects of motivic and equivariant homotopy theory, and the generalisations of these tools and techniques in the setting of non-commutative geometry.

INVITED SPEAKERS

The Summer School will feature mini-courses by

*  Clark Barwick (University of Edinburgh)
*  Teena Gerhardt (Michigan State University)
*  Daniel Isaksen (Wayne State University)
*  Dmitry Kaledin (Steklov Mathematical Inst. & National Research Univ. Higher School of Economics)
*  Marc Levine (Universität Duisburg-Essen)
*  Ivan Panin (St. Petersburg Department of Mathematics)
*  Goncalo Tabuada (MIT/University of Warwick)

as well as research talks by

*  Federico Binda (University of Milan)
*  Tom Bachmann (MIT)
*  Mike Hill (UCLA)
*  Geoffroy Horel (University Paris 13)
*  Alexander Neshitov (Western University)
*  Angélica M. Osorno (Reed College)
*  Marco Robalo (Institut de Mathématiques de Jussieu)
*  Kirsten Wickelgren (Duke University)

 

Both the lecture series and research talks will focus on presenting the latest developments in topics related to categories of motives, calculational and foundational aspects of motivic and equivariant homotopy theory, and the generalisations of these tools and techniques in the setting of non-commutative geometry.

This is an IHES Summer School organised in partnership with the Research Council of Norway, the Fondation Mathématique Jacques Hadamard and the ANR, and the support of the Société Générale and the ERC.
