»Rigidity of spin fill-ins with non-negative scalar curvature«

Abstract:
I will present new mean curvature rigidity theorems of spin fill-ins with non-negative scalar curvature using two different spinorial techniques. The first technique is based on extending boundary spinors satisfying a generalized eigenvalue equation via the Fredholm alternative for an APS boundary value problem, while the second is a comparison result in the spirit of Llarull and Lott using index theory. Our results address two questions by Miao and Gromov, respectively. This is joint work with Sven Hirsch and Rudi Zeidler.
