| Title: | On certain $C^0$-aspects of contactomorphism groups |
| Speaker: | Vukasin Stojisavljevic, CRM, Universite de Montreal |

| Abstract: | |
| We will study $C^0$-dynamic of contactomorphisms of certain prequantization spaces. In particular, we will show dynamical footprints of the famous squeezing vs (non-)squeezing dichotomy in contact topology as well as define new metrics on contactomorphisms and, more generally, contact homeomorphisms. The main technical ingredient is a result about $C^0$-continuity of actions of translated points of contactomorphisms. The talk is based on a joint work in progress with Baptiste Serraille. | |
