Finite embeddability of groups and its applications to geometry and topology
Location: MSRI: Simons Auditorium
fixed point properties
hyperbolic groups and generalizations
We will introduce the concept of finite embeddability of groups and discuss its applications to non-rigidity of topological manifolds and the moduli space of positive scalar curvature metrics. A certain secondary invariant of elliptic operators plays a crucial role in these applications. This is joint work with Shmuel Weinberger and Zhizhang Xie
