The amplituhedron is a remarkably elegant geometric object that was discovered in 2013 in the context of studying scattering amplitudes in theoretical particle physics (specifically, in planar N = 4 super Yang-Mills theory). It presents a radically different way to calculate fundamental quantities in quantum field theory, in which long-standing principles such as unitarity and […]

The Swiss Federation of Mathematical Games (FSJM, https://fsjm.ch/en/home/) is a non profit association that promotes the study and practice of mathematics in Switzerland, through appropriate recreational means. The activities of the FSJM contribute to the promotion of MINT disciplines, in particular towards girls. One of such activities is the Championship of Mathematical and Logical Games, for […]

Algebraic K-theory is one of the central and ubiquitous objects of modern mathematics. It plays an important role in such diverse fields as number theory, geometry, and mathematical physics. One characteristic feature of it is that, more often than not, algebraic K-theory is immensely hard to describe explicitly. A variety of conjectures have been proposed […]

Moduli of varieties and sheaves 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 eld, which are complemented by colloquium style talks and contributions from junior participants. The theme for […]

Alps II The ALPS (Advanced Lectures in Physics in Switzerland) is a series of junior schools in theoretical physics taking place in the Swiss Mountains. Its principal aim is to lay the foundation for fruitful collaborations between young researchers with a variety of backgrounds. It is achieved by inspiring discussions between students and through lectures […]

Most of theoretical biology is currently restricted to modeling and statistical analysis. However, mathematicians and theoretical physicists increasingly search for general principles underlying life, and several instances of mathematical insights about biological facts have appeared recently. For example, the proposers have studied the principles of mechanics and evolution of allosteric proteins (JPE, [1]) and the […]

Despite their complexity, strongly correlated quantum and classical many-body systems have simpler effective descriptions when looking at behaviours that happen at long times or large distances. Intuitively, this is because of “thermalisation”, and related notions: the accumulation, over time and space, of a large number of complex interactions amongst local degrees of freedom, “washes out” […]

This summer school focuses on exciting recent developments at the intersection of geometric group theory and algebraic topology. The full force of the tools and ideas in the interplay between these two subjects have yet to be exploited. The aim of this school is to expose young researchers to the results and questions arising from […]

  Les Marmottes – Filles et Maths (SRS, 21-25 April 2025) Les Marmottes – Filles et Maths is an introductory one week-course in mathematical research (FR) in Les Diablerets that has been running since 2023, organised by Sandie Moody (teacher at Collège de Genève) and Elise Raphael (scientific assistant at UNIGE), both of whom hold […]

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.

Workshop in Mathematical Physics is aimed at introducing graduate students and postdocs to current developments in the field. This is a recurring workshop, held in Les Diablerets every February since 2005. It covers current developments in mathematical physics and realted areas, rotating the subject over the years. The emphasis will be on hot topics, to […]

This is an international camp aimed at preparing students for the European Girls’ Mathematical Olympiad (EGMO). Each country will bring their EGMO team and a speaker, and the speaker from each country will teach one preparation session (morning or afternoon) in an area within algebra, geometry, number theory, and combinatorics. There will also be a […]

Tremendous progress has been made in the field of differential equations, including partial differential equations with noise. Fuelled by new techniques and modelling requirements, we can now handle a broader range of stochastic differential equations and stochastic partial differential equations. For instance, the solution theory for the KPZ equation and its cousin, the Stochastic Heat […]

The conference “Statistical mechanics, Algebra, and Geometry” aims to unite researchers interested in quantum gravity and its rich relations to von-Neumann algebras on the hand, and statistical mechanics approaches, such as Eigenstate Thermalization (ETH), as well as other manifestations of quantum chaos, on the other. The main goal of this conference is to assemble a […]

Problems in Extremal and Probabilistic Combinatorics seek to understand the maximum/minimum value attainable by one parameter of a discrete structure assuming only the value of another parameter of that structure. The discrete structure can be either deterministic, or drawn from some distribution. For example, the discrete structure can be a graph, and the question can […]

BPS states provide a computable sector for addressing fundamental questions on non-perturbative dynamics in both gauge theory and string theory. Significant progress on this subject has emerged in recent years from various directions of research, spurred by foundational work on Wall-Crossing within the past decade. The workshop will focus on the most recent developments on […]

The theory of resurgence was developed to provide a deeper understanding of asymptotic series in various fields of mathematics. More recently, this theory has been applied to problems in geometry and topology, leading to a new perspective on enumerative invariants in three-manifold topology and in algebraic geometry. A remarkable synthesis is emerging, relating analytic invariants […]
