|TITLE||Hochschild entropy and categorial entropy|
|ABSTRACT|| In this talk, I will talk about categorical entropy, which is introduced by Dimitrov-Haiden-Katzarkov-Kontsevich, via homological mirror symmetry of K3 surfaces. We show the existence of a symplectic Torelli mapping class of positive categorical entropy, which is a counterexample of Gromov-Yomdin type conjecture. Furthermore, I will introduce the notion of Hochschild entropy and related topics.
