Stability of Geodesic Spheres in ${\mathbb{S}}^{n+1}$ under Constrained Curvature Flows

Abstract

In this paper we discuss the stability of geodesic spheres in ${\mathbb{S}}^{n+1}$ under constrained curvature flows. We prove that under some standard assumptions on the speed and weight functions, the spheres are stable under perturbations that preserve a volume type quantity. This extends results by Escher and Simonett, 1998, and the author, 2015, to a Riemannian manifold setting.
