Invariant Submanifolds of a Generalized Kenmotsu Manifold

Abstract

In this paper, invariant submanifolds of a generalized Kenmotsu manifold are studied. Necessary and sufficient conditions are given on a submanifold of a generalized Kenmotsu manifold to be an invariant submanifold.In this case, we investigate further properties of invariant submanifolds of \ a generalized Kenmotsu manifold. In addition, some theorems are given related to an invariant submanifold of a generalized Kenmotsu manifold.We consider semiparallel and 2-semiparallel invariant submanifolds of a generalized Kenmotsu manifold.
