Geometric realizations of mapping class groups and circle groups

Special Events

Speaker: Vladimir Markovic, University of Warwick
Location: 1147 MSB
Start time: Mon, Jan 30 2006, 2:00PM

In this talk I will describe the problem of lifting the mapping class group of a given manifold to the corresponding group of homeomorphisms and state some known application to low dimensional topology (up to the dimension four). I will also talk about the analytical aspects of this problem. Various applications will be mentioned including the classification of transitive circle groups.
