Title: Categorical entropy and symplectic geometry

 

Abstract:

A symplectic manifold together with a symplectomorphism form a discrete dynamical system. To study the complexity of such a dynamical system, one can use various kinds of entropies: topological entropy, Floer-theoretic entropy, categorical entropy and so on. In this talk, I will focus on the categorical entropy and give some examples from symplectic geometry. This talk consists of the following four parts:
1. From topological entropy to categorical entropy
2. Entropy of compositions of spherical twists
3. Entropy via spherical functors
4. Towards a categorical Gromov--Yomdin theorem
Part 3 is based on arXiv:2102.08590 and Parts 2, 4 are based on joint works in progress with Federico Barbacovi.
