This is a five day workshop with the uniting theme “Groups and group actions”. Each day focuses on a specific topic and will be planned by an experienced colleague together with early stage researchers.

A recurring theme in algebra and topology is the study of algebraic structures associated to manifolds, with the goal of finding invariants, and understanding automorphisms. Examples include the study of the Grothendieck-Teichmüller- and related groups in algebra, string topology and its invariance properties, and configuration spaces and the Goodwillie-Weiss embedding calculus in topology. Recent progress […]

A gauged map u is a generalization of a morphism Y → X between almost complex manifolds that takes into account a given symmetry under some group G on the target X. It is natural to consider objects that are invariant under this symmetry, assumed Hamiltonian, and a most sensible extension is to promote u […]

It has become clear over the last few years that working in a sector of large quantum number leads to significant simplifications in strongly coupled theories which are otherwise inaccessible to analytic methods. At large charge, it is for example possible to calculate the conformal data of CFTs with a global symmetry. The field has […]

Non-locality is by now a well established field, both within foundations of quantum physics and in quantum information science. However, non-locality in networks is a new burgeoning field, triggered by ”old” (Bell) nonlocality and by the prospect of future quantum network that will connect quantum processors and deliver, among others, informationally secure cryptography.

Recently, the AdS/CFT duality for the case of AdS3/CFT2 has been understood in quite some detail. In particular, a solvable world-sheet theory has been identified that has been argued to be exactly equivalent to the dual free symmetric orbifold CFT.

The purpose of this conference is to bring together experts in Poisson Geometry, Geometric Representation Theory, and Conformal Field Theory to discuss the recent progress and various interactions of these highly active areas of research.

Recent days have seen a rapid developments on shifted Poisson and symplectic structures on (derived) differentiable or algebraic stacks. A differentiable stack is, roughly speaking, a Lie groupoid up to Morita equivalence, and the stack represented by a symplectic groupoid of a Poisson manifold naturally has a 1- shifted symplectic structure.

Link homology theories emerged about 20 years ago with the celebrated Khovanov homology and Heegaard–Floer homology. These theories categorify respectively the Jones polynomial and the Alexander polynomial, the two most famous polynomial link invariants. These theories are likely to become an essential building block in the seek for a 3+1 quantum field theory (but many hard steps are still to […]

This conference aims to bring together physicists and mathematicians interested in low-dimensional examples of holographic dualities, the orbit method and their interplay via the quantization of coadjoint orbits of the Vi- rasoro group.

The Euler summer school is an event organized every year for all students of the Euler course, an EPFL program for highly gifted youth in mathematics aged 12 to 18 years.

In the last years, there has been important progress in the mathematical understanding of effective theories for interacting quantum gases and classical fluids. Notable examples are Gross-Pitaevskii theory for Bose-Einstein condensates, and the Boltzmann equation for rarefied gases.
