A long neck principle for Riemannian spin manifolds with positive scalar curvature

Simone Cecchini (Göttingen)

We develop index theory on compact Riemannian spin manifolds with boundary in the case when the topological information is encoded by bundles which are supported away from the boundary. As a first...

A relative Cheeger-Gromov rho-invariant and the space of positive scalar curvature metrics on manifolds with boundary

Mehran Seyedhosseini

Secondary invariants associated to positive scalar curvature metrics on closed spin manifolds have been used to study the space of such metrics on a fixed manifold. I will first talk about a result of...
