In this paper, the concepts of screen slant and semi-slant lightlike submersions from an indefinite Sasakian manifold onto a lightlike manifold are introduced. Examples are provided and characterization theorems for the existence of such lightlike submersions are obtained. The integrability conditions of distributions involved in the definitions of both classes of lightlike submersions are also investigated.
In this paper, we introduce the notions of screen slant and semi-slant lightlike submersions from an indefinite Sasakian manifold onto a lightlike manifold. We give examples and obtain characterization theorems for the existence of such lightlike submersions. We also investigate the integrability conditions of distributions involved in the definitions of both classes of lightlike submersions.
