Special half lightlike submanifolds of an indefinite Sasakian manifold

Abstract

In this paper, we study the geometry of half lightlike submanifolds of an indefinite Sasakian manifold. There are several different types of half lightlike submanifolds of an indefinite Sasakian manifold according to the form of its structure vector field. We study two types of them here: tangential and ascreen half lightlike submanifolds.

Keywords: tangential and ascreen half lightlike submanifold, totally umbilical, screen conformal, indefinite Sasakian manifold
