A softer connectivity principle

Differential Geometry 2020-01-08 v2

Abstract

We give soft, quantitatively optimal extensions of the classical Sphere Theorem, Wilking's connectivity principle and Frankel's Theorem to the context of k{k}-th Ricci curvature. The hypotheses are soft in the sense that they are satisfied on sets of metrics that are open in the C2C^{2}-topology.
