Warped product pseudo-slant submanifolds of quasi-Sasakian manifolds

Abstract

The object of the present paper is to study warped product and doubly warped product pseudo-slant submanifolds of quasi-Sasakian manifolds. We derive an example of proper pseudo-slant submanifold of almost contact metric manifold. Also, we study the non-existence of warped product and doubly warped product pseudo-slant submanifolds of quasi-Sasakian manifolds.
