New properties on normalized null hypersurfaces

Cyriaque Atindogbe, Manuel Gutiérrez, Raymond Hounnonkpe

Rigging technique introduced in \cite{bi0} is a convenient way to address the study of null hypersurfaces. It offers in addition the extra benefit of inducing a Riemannian structur…

Lightlike Osserman submanifolds of semi-Riemannian manifolds

Cyriaque Atindogbe, Oscar Lungiambudila, Joël Tossa

In this paper, we study Jacobi operators associated to algebraic curvature maps (tensors) on lightlike submanifolds M. We investigate conditions for an induced Rie- mann curvature…

Einstein-Weyl structures on lightike hypersurfaces

Cyriaque Atindogbe, Lionel Bérard Bergery

We study Weyl structures on lightlikes hypersurfaces endowed with a conformal structure of certain type and specific screen distribution: the Weyl screen structures. We investigate…

A note on conformal connections on lightlike hypersurfaces

Cyriaque Atindogbe, Lionel Bérard Bergery

Degenerate submanifolds of pseudo-Riemannian manifolds are quite difficult to study because there is no prefered connection when the submanifold is not totally geodesic. For the pa…

-tensors on lightlike hypersurfaces

Cyriaque Atindogbe, Lionel Bérard Bergery

This paper introduces $\anabla$-tensors on lightlike hypersurfaces of signature , and investigates on their properties in connection with the null geom…

Reduction of the co-dimension of light-like isotropic sub-manifolds

Cyriaque Atindogbe, Jean-Pierre Ezin, Joël Tossa

We give a sufficient condition for a lightlike isotropic submanifold , of dimension , which is not totally geodesic in a semi-Riemannian manifold of constant curvature an…
