Screen transversal conformal half-lightlike submanifolds

Abstract

In this paper, we study half-lightlike submanifolds of a
semi-Riemannian manifold such that the shape operator of screen distribution is conformal to the shape operator of screen
transversal distribution. We mainly obtain some results concerning the induced Ricci curvature tensor and the null sectional curvature of screen transversal conformal half-lightlike
submanifolds.
