Seminar “Modern Mathematical Physics”

Date and Time: Tuesday, 30 June 2020, at 1:00 PM

Venue: Online conference on Zoom, Bogoliubov Laboratory of Theoretical Physics

Seminar topic: «Critical configurations of clusters of solids»

Speaker: Oleg Ogievetsky (BLTP & Marseille University)

Abstract:

We study varieties M of clusters of solids. A critical cluster is a critical point X of some function F on such a manifold. The specificity of the situation is that X is not a Morse critical point. Even worse: at the point X, the function F is usually not smooth, and can even be discontinuous. We discuss examples of critical clusters and discuss some theorems and open questions.
