CHARACTERIZATION OF GCR-LIGHTLIKE WARPED PRODUCT OF INDEFINITE KENMOTSU MANIFOLDS

In this paper we prove that there do not exist warped product GCR-lightlike submanifolds in the form M = N-T x(lambda) N-T such that N-T is an anti-invariant submanifold tangent to V and N-T an invariant submanifold of <(M)overbar)>, other than GCR-lightlike product in an indefinite Kenmotsu manifold. We also obtain some characterizations for a GCR-lightlike submanifold to be locally a GCR-lightlike warped product.
