ON TOTALLY UMBILICAL CR-SUBMANIFOLDS OF A KAEHLER MANIFOLD
摘要
Let M be a compact 3-dimensional totally umbilical CR-submanifold of a Kaehler manifold of positive holomorphic sectional curvature. We prove that if the length of the mean curvature vector of M does not vanish, then M is either diffeomorphic to S^3 or RP^3 or a lens space L^3_(p,q).
