What is the submanifold is an important research field of differential geometry.In this paper,we study subcurvatures with parallel mean curvature vector.The main conclusion is:Let Nn+P be a hypersurface in Euclidean space Rn+p+1,Mn is the parallel submanifold of the compact boundless average curvature vector in Nn+p.If the main curvature ? of Nn+p satisfied:c1?|?|?c2(c1,c2>0),then there is fM[(2-1/p)S2+n|H|S3/2-nc12S+c22n2H2}*1?0.Where S is the square of the mod-ule length of the second basic from of submanifold,and H is its average curvature.This is,we get a Simons type integral inequality. |
