Centrally extended mapping class groups from quantum Teichmüller theory

Number of pages23
Publication date2010
Abstract

The central extension of the mapping class groups of punctured surfaces of finite type that arises in quantum Teichm"uller theory is 12 times the Meyer class plus the Euler classes of the punctures. This is analogous to the result obtained in cite{FS} for the Thompson groups.
