January 13 - April 17, 2025
Organizers: Ursula Hamenstädt, Yevgeny Liokumovich, Andrea Mondino, Stephan Stadler, Stefan Wenger, Robert Young
Description: In recent years, the development of analytic tools to study geometric questions in metric spaces beyond Riemannian manifolds has seen tremendous progress and led to many structural results which shed a new light even on classical questions. The goal of this HIM program is to further refine such tools and explore their applications, like the study of filling invariants, norms, volumes, energies, in various concrete geometric frameworks.
The program aims at bringing together researchers in analysis on metric spaces, geometric group theory, differential geometry, higher Teichmüller theory and low dimensional topology to isolate and enhance common core ideas and tie these strands to a more global theory, geared at making progress towards some well established open problems.
The trimester will include
- an Introductory Winter School "Analysis and geometry on groups and spaces" (January, 27-31),
- an International Conference "Differential geometry beyond Riemannian manifolds” (March, 24-28),
- and the Felix Klein Lectures (March, 31 to April, 11).

Description: Studying smooth shapes with the aid of differential calculus is at the core of classical differential geometry. The interest in more general objects arises from the incompleteness of the space of smooth shapes and the existence of intriguing groups lacking suitable smooth models.
Metric measure spaces with synthetic curvature bounds provide a suitable generalization of Riemannian manifolds. Analysis in these spaces recovers significant portions of classical Euclidean geometric function theory. This analytical toolbox allows the extension of differential geometric ideas into the broader realm of metric measure spaces.
In this spirit, the conference will concentrate on presenting new results and developments for both smooth and non-smooth spaces.
