一类近切触流形的余维数为2的不变子流形

INVARIANT SUBMANIFOLD OF CODIMENSION 2 OF A CERTAIN CLASS OF ALMOST CONTACT MANIFOLDS

本文研究了由Ｋ．Ｋｅｎｍｏｔｓｕ引进的一类近切触Ｒｉｅｍａｎｎ流形的余维数为２的不变子流形，证明不变子流形也是此类近切触流形．

This paper studies invariant submanifold of codimension 2 of Kenmotsu manifold. We obtain the structure tensors induced on the submanifolds of codimension 2. Furthermore we obtain some geometric properties of the invariant submanifold of codimension 2.
