摘要
We prove that there do not exist CR submanifolds M n of maximal CR dimension of a complex projective space P n+ p 2 (C) with flat normal connection D of M, when the distinguished normal vector field is parallel with respect to D. If D is lift- flat, then there exists a totally geodesic complex projective subspace P n+ 1 2 (C) of P n+ p 2 (C) such that M is a real hypersurface of P n+ 1 2 (C).
