The asymptotic geometry of mapping class groups and application
I shall describe the asymptotic geometry of the mapping class group, in particular its tree-graded structure and its equivariant embedding in a product of trees. This can be applied to study homomorphisms into mapping class groups defined on groups with property (T) and on lattices in semisimple groups. The talk is based upon two joint works with J. Behrstock, Sh. Mozes and M. Sapir.
