SEMINARI DI GEOMETRIA 14:30-15:30, Sala Seminari (Dip. Matematica) Bounded cohomology and simplicial volume of generalized Dehn fillings Cristina Pagliantini (Università di Regensburg)

Abstract:

Bounded cohomology was developed by Gromov in 1982 in order to study the simplicial volume, a homotopy invariant of compact manifolds. We present isometric properties of bounded cohomology and as an application we provide an estimate of simplicial volume of generalized Dehn fillings.

This is a joint work with M.Bucher, M.Burger, A.Iozzi, R.Frigerio and M.B.Pozzetti.
