The linear instability of some families of Einstein metrics

Abstract: I will report some works on the linear stability question of Einstein metrics. We proved the linear instability of some Einstein metrics with positive scalar curvature, including some families of Riemannian manifolds with real Killing spinors, and low-dimensional homogeneous Einstein spaces. The talk is based on joint works with McKenzie Wang and Uwe Semmelmann.

Virtual seminar on geometry with symmetries

Series comments: Description: Research seminar in Lie group actions in Riemannian geometry.

The seminar meets every other Wednesday. To accommodate most time zones, the time rotates. The Zoom link is sent to the mailing list around 24 hours before each talk. To subscribe to the mailing list, send a message to geometrywithsymmetries@gmail.com requiring it.
