The mapping class group (in short, MCG) of a surface is a fundamental object of study in topology and in geometry, where it is regarded as the orbifold fundamental group of the moduli space of Riemann surfaces homeomorphic to the surface.

The aim of this workshop is to bring together researchers from both physics- in topological quantum field theory, high energy physics, and condensed matter- and mathematics- higher categories, representation theory, and topology- to report on recent progress and open questions in the study of generalised notions of symmetry. There have been significant recent developments in […]

In the last few years there has been enormous progress in the rigorous understanding of the emergence of macroscopic effective theories for many-particle systems. This event aims at gathering researchers working on many-body classical and quantum systems, as well as on the analysis of nonlinear partial differential equations describing effective models. The workshop will give an overview of […]

Recently, there were three major breakthroughs in the field of integrable systems in mathematical physics: one within the area of classical systems, one concerning quantum systems, and one about algebraic integrability. This workshop brings together the leading senior and junior researchers of these areas with the aim to give them the opportunity to present their results, discuss ongoing projects, and […]

The HAGS started in 2013, and has been a major cohesive activity in Algebraic Geometry in Switzerland ever since. The core of the workshop is 3-4 lecture series given by top experts in the field, which are complemented by colloquium style talks and contributions from junior participants. Theme for 2023: Current developments in the moduli […]

This workshop aims at bringing together mathematicians making use of analytic methods in their study of dynamics, geometry, PDEs, or inverse problems. In the past twenty years, microlocal and functional analysis techniques have encountered a large success both in hyperbolic dynamics and geometry as they turned out to be ripe enough to tackle unsolved problems […]

This conference will bring together students and close collaborators of Peter Teichner on the occasion of his sixtieth birthday. With Teichner’s contributions to both Low-dimensional Topology and Quantum Field Theory, this will be an opportunity to share ways of thinking between experts of these two areas. The accent will be on recent results which will […]

Quantum Hall effect, discovered in the 1980s, continues to this day to attract enormous interest among both physicists and mathematicians. With its nontrivial connections to modern theoretical physics, analysis, geometry, probability and hydrodynamics, the subject can be counted on to provide novel insights, problems, ideas and collaboration prospects for respective communities. The topics to be discussed at this workshop […]

The conference follows a long tradition of schools and workshops on Geometric Group Theory and beyond  in the Swiss Alps. The 2023 edition will be an occasion to celebrate the 70-th birthday of Slava Grigorchuk.

More information about this event can be found here.  

Non-Archimedean geometry provide a natural setting to study degenerations in various contexts. The aim of this workshop is to bring together researchers coming from different fields of mathematics but related by the use of non-Archimedean geometry. They will share with each other their experience and points of view on this subject. More precisely the following […]

Solving a strongly interacting quantum system, even with simplified interactions, turns out to be a challenging task. It requires the application of techniques from a variety of mathematical disciplines such as algebra, representation theory, geometry and topology, etc. On the other hand, exact solutions provide unparalleled insight into interesting phenomena in quantum many-body systems and […]

The theory of resurgence was introduced by Jean Ecalle in the 1980’s, partially motivated by the study of perturbative series in quantum theory. In the last years, there has been a renewed interest in this theory.
