Some isolation and stability results for Einstein manifolds

In this paper, we prove new isolation and stability results for Einstein manifolds in a variety of settings. By imposing conditions on the Weyl tensor, we establish new stability criteria for compact, asymptotically hyperbolic (AH) and asymptotically locally Euclidean (ALE) manifolds and an isolation result in the latter setting. For compact Kähler and Sasaki [Formula: see text]-Einstein manifolds, we provide similar results which involve the Bochner tensor and the contact Bochner tensor, respectively.
