buondì, segnalo con colpevole ritardo il seminario di geometria di oggi, sempre in aula seminari alle 16. Bruno Martelli ---- SEMINARI DI GEOMETRIA Titolo: Relative bounded cohomology for groupoids Wednesday, February 11, 2015 Ora Inizio: 16:00 Ora Fine: 17:00 Aula: Sala Seminari (Dip. Matematica) Relatore: Matthias Blank (Regensburg) Bounded cohomology is a functional analytic modification of regular cohomology, with applications to geometry, topology and (geometric) group theory. After giving a very short introduction to groupoids, I will present our construction of (relative) bounded cohomology for (pairs) of groupoids. This includes a natural setting for bounded cohomology relative to a family of subgroups. Finally, I will discuss a relative version of Gromov's mapping Theorem in this context.
