Title: Simplicial volume and Gromov's main inequality
Abstract: Since its introduction in the early 1980’s by Gromov the
simplicial volume has been central to the investigation of the
relationship between the large scale geometry and the topology of
manifolds. The most fundamental theorem in this subject is Gromov’s Main
Inequality which bounds the simplicial volume of a manifold M, a purely
homological invariant, by its Riemannian volume provided M satisfies a
lower Ricci curvature bound.
In this talk we address some curvature-free estimates in the spirit of the
main inequality.
Tutti gli interessati sono invitati a partecipare.
