Abstract: | In this paper we study the role of constant vector fields on a Euclidean space R n+p in shaping the geometry of its compact submanifolds. For an n-dimensional compact submanifold M of the Euclidean space R n+p with mean curvature vector field H and a constant vector field on R n+p , the smooth function is used to obtain a characterization of sphere among compact submanifolds of positive Ricci curvature (cf. main Theorem). |
