Radical transversal screen pseudo-slant lightlike submersions from indefinite Sasakian manifolds onto lightlike manifolds.

As a generalization of transversal and radical transversal screen slant lightlike submersions, we introduce the notion of radical transversal screen pseudo-slant lightlike submersions from indefinite Sasakian manifolds onto lightlike manifolds with examples. We obtain an existence theorem for such lightlike submersions and study the geometry of distributions involved in the definition. [ABSTRACT FROM AUTHOR]
