Radical invariant lightlike hypersurfaces of almost product-like statistical manifolds

Ö. Aksu, E. Erkan, M. Gülbahar

Introducing a new class of submanifolds is one of the key concepts in submanifold theory of semi-Riemannian manifolds. The purpose of this study is to introduce radical invariant lightlike hypersurfaces of almost product-like Lorentzian manifolds. Some examples of these hypersurfaces are presented herein. The main identities admitting Riemannian curvature tensor fields of these hypersurfaces are established with the aid of statistical structures.
