报告摘要:In this talk, we consider the evolution of locally uniformly convex graph defined on a convex open domain of Euclidean space by curvature flow, for which the normal speed is given by a power of a monotone, symmetric, homogeneous of degree one function F of the principal curvatures. Under the assumption that F is inverse concave and its dual function approaches zero on the boundary of positive cone, we prove that the complete smooth strictly convex solution exists and remains a graph until the maximal time of existence. For a class of special curvature functions, longtime existence of this flow can be obtained.
