Mini Workshop "Positive Geometry"

by Bernd Sturmfels (MPI-MiS Leipzig), Hofie Hannesdottir (IAS Princeton), Johannes Henn (Max-Planck-Institut für Physik ), Lizzie Pratt (UC Berkley), Simon Telen (CWI Amsterdam)

Monday 23 Jan 2023, 16:00 → 18:00 Europe/Berlin

Mathematics-Informatics Building, Hall 3 (Technical University of Munich)

There are strong indications from physics at both infinitesimal and cosmic distances that our current understanding of the laws of nature is only approximate, and must be replaced by deeper principles. Novel geometric objects, in the setting of amplituhedra and Feynman integrals, hint at new mathematical structures. Combinatorics and algebraic geometry have been connected to particle physics and cosmology in an entirely unexpected way. This seminar is an invitation to join the discussion.

Bernd Sturmfels, Director at the Max Planck Institute for Mathematics in the Sciences in Leipzig, is organizing the workshop in collaboration with the SFB/Transregio 109, Discretization in Geometry and Dynamics as well as with Johannes Henn, Director at the Max Planck Institute for Physics in Munich.

If you wish to attend, there is no registration necessary. The event is aimed at scientists with a bachelor's degree and higher from all relevant disciplines.
