Events

We are pleased to announce the twentieth edition of the annual GAP (Geometry and Physics — Séminaire itinérant) conference and summer school, which will take place at RIMS, Kyoto, Japan, from April 13 to 24, 2026. GAP XX will be organized as part of the RIMS Research Project 2026–2027 on "Higher Structures in Geometry and Mathematical Physics." The program will span two weeks: April 13–17, 2026 — School on Moduli Spaces in Various Flavors of Geometry (mini-courses); April 20–24, 2026 — Workshop on Moduli Spaces in Various Flavors of Geometry. Further details, including the list of speakers and registration information, are available on the conference website: https://sites.google.com/view/gap2026/home

Date: April 15, 2026 (Wednesday) at 4PM (UK time) Speaker: Prof. Harald Andrés Helfgott, Paris City University, France Topic: Growth, expansion and escape in groups Prof. Harald Helfgott is a leading mathematician who made fundamental contribution to number theory, group theory, and additive combinatorics. He is widely known for his proof of the ternary Goldbach conjecture, as well as for foundational contributions to the study of growth and expansion phenomena in groups. In this talk, he will discuss growth and expansion in groups, including progress toward the celebrated Babai conjecture on the diameters of finite simple groups. See the blog announcement of this talk for more details.

This AI and Data Science Congress goes beyond purely technical disciplines, bringing together fundamental drivers that are reshaping the paradigms of the modern world, from mathematics and engineering to health and social sciences.

The workshop "Valentia Geometrica 2026" is scheduled for 20-23 April 2026, and the plan is to cover topics on Geometric Analysis in a broad sense, as a crossroad between Differential Geometry, Partial Differential Equations, Calculus of Variations, Geometric Measure Theory, Metric Geometry,...

The study of fluid flows on Riemannian manifolds generalizes the classical theory of fluid dynamics in Euclidean space to curved spaces. This extension is motivated both by applications and by intrinsic mathematical interest in the interplay between partial differential equations and differential geometry. Central to this theory is the formulation of the Navier-Stokes equations on a Riemannian manifold, which describe viscous fluid motion subject to the geometry of the underlying space. Some basic questions are: (Formulation) How should the Navier-Stokes equations be correctly expressed on a general Riemannian manifold? (Well-posedness) Do the standard questions of existence, uniqueness, and regularity of solutions extend naturally to manifolds? Deadline for application: 15 February 2026

In this seminar leading experts introduce key elements of mathematical knot theory and discuss physical applications, from vortex dynamics to magnetic fields, from polymer physics to proteins and DNA biology. Topics include an introduction to knots, links and braids, knot invariants and related algebraic structures. From knotoids and linkoids to the real world of physical entanglements, the mathematical tools of knot theory become essential to describe natural phenomena around us.

The Computers in Scientific Discovery (CSD) conference series is designed to bring together researchers whose work makes connections between mathematics, computer science, and natural sciences. In particular, the CSD meetings have concentrated on how algorithms, mathematical software and data are used in non-trivial ways to advance research in the mathematical and physical sciences. The conferences focus not only on applications, but also on mathematical foundations, philosophy and practicalities of the scientific discovery process, including conjecture-making, construction and the use of curated databases of mathematical objects, and computer-aided proofs. The main theme of the 11th CSD conference is ‘Computationally Intensive Methods in Mathematics: Applications in Chemistry and Beyond’. The conference will take place 4–8 May 2026 in picturesque Kranjska Gora, Slovenia.
