Title: Rigidity phenomena in Billiard and Hamiltonian Dynamics
Abstract: In this talk I shall address several rigidity questions appearing in the study of billiard maps and Hamiltonian dynamical systems, with a particular focus on their integrability and their action-spectral properties.

Title: Around a Question of Entov-Polterovich-Py
Abstract: In this talk I will
discuss a celebrated question posed by Entov, Polterovich and Py on
quasimorphisms. First I will explain my partial answer to this question
which is based on my preprint and then I will explain other phenomena
related to this topic which is a joint work with Egor Shelukhin.
