Title: Asymptotically rigid mapping class groups

Abstract: During this talk we will focus on a family of asymptotically rigid mapping class groups which includes a braided version of Ptolemy-Thompson groups. We will build a contractible cube complex on which these groups act and we will see which kind of properties can be deduced from this action.
