PRESCRIBED MEAN CURVATURE OF SPACELIKE HYPERSURFACES IN COSMOLOGICAL SPACETIME
摘要
Abstract
In this paper,we study the modified mean curvature flow in cosmological space time.We obtain a limiting spacelike hypersurfaee whose mean curvature is equal to a given function by estimating the surfaces' geometric quantities including the height,gradient and the curvature functions.关键词
