On a family of Einstein like Walker metrics
Issa Allassane Kaboye, Mamadou Ciss, Abdoul Salam Diallo
A four dimensional pseudo-Riemannian manifold of signature (2, 2) is called a Walker manifold if it admits a parallel degenerate plane field. In this paper, we study the curvature…

Half-Lightlike Submanifold of a Lorentzian Manifolds with a conformal co-screen distribution
Issa Allassane Kaboye, Mahamane Mahi Harouna, Bazanfaré Mahaman
In this paper, we give the Cartan's formula for half-lightlike submanifolds of Lorentzian manifolds and use it to show that a screen homothetic half-lightlike submanifolds of a Lor…
