Abstract:The purpose of this paper is to investigate the convergence of the volume-preserving mean curvature flow of closed hypersurfaces in space forms. Assume that the initial hypersurface satisfies suitable integral curvature pinching conditions. We prove that along the volume-preserving mean curvature flow the initial hypersurface will be deformed to a totally umbilical sphere.The basic property of flow (1.1) is its isoperimetric nature. Namely, in the case that M t is embedded along the flow, the (n + 1)-dimension… Show more
“…For example, there are Huisken's volume-preserving mean-curvature flow [12] and McCoy's surface-area-preserving mean-curvature flow [17]. Recently, the study of non-local flow was extended to the case of the Riemannian manifold; see [25].…”
The convergence and blow-up results are established for the evolution of non-simple closed curves in an area-preserving curvature flow. It is shown that the global solution starting from a locally convex curve converges to an m-fold circle if the enclosed algebraic area A0 is positive, and evolves into a point if A0 = 0.
