Stability of the Non-Symmetric Space $E_{7} / PSO (8)$

Paul Schwahn, Uwe Semmelmann, Gregor Weingart

We prove that the normal metric on the homogeneous space $E_{7} / PSO (8)$ is stable with respect to the Einstein-Hilbert action, thereby exhibiting the first known example of…

Coindex and rigidity of Einstein metrics on homogeneous Gray manifolds

Paul Schwahn

Any $6$ -dimensional strict nearly Kähler manifold is Einstein with positive scalar curvature. We compute the coindex of the metric with respect to the Einstein-Hilbert functional o…
