局部积流形的半不变子流形

SEMIINVARIANT SUBMANIFOLDS OF A LOCALLY PRODUCT MANIFOLD

讨论局部积流形的半不变子流形，给出了半不变子流形上局部为不变子流形和反不变子流形的黎曼积的两个条件．

This paper studies the semiinvariant submanifolds of a locally product manifold, two conditions for semiinvariant submanifold to be a Riemannian product of an invariant submanifold and an antiinvariant submanifold locally are given.
