Abstract: I will start with an introduction to Thompson groups and their surface version. Then I will explain how one can determine their finiteness properties by calculating the connectivity of some special complexes. This is based on joint works with Javier Aramayona, Julio Aroca, Kai-Uwe Bux, María Cumplido, Jonas Flechsig, Nansen Petrosyan and Rachal Skipper.
