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…
2-Ruled Hypersurfaces in a Walker 4-Manifold
Mohamed Ayatola Dramé, Ameth Ndiaye, Abdoul Salam Diallo
The hypersurface is one of the most important objects in a space. Many authors studied diffrent geometric aspects of hypersurfaces in a space. In this paper, we define three types…
Four-dimensional semi-Riemannian Szabó manifolds
Abdoul Salam Diallo, Punam Gupta
In this paper, we prove that the deformed Riemannian extension of any affine Szabó manifold is a Szabó pseudo-Riemannian metric and vice-versa. We proved that the Ricci tensor of a…
Einstein doubly warped product manifolds with a semi-symmetric metric connection
Punam Gupta, Abdoul Salam Diallo
In this paper, we study the doubly warped product manifolds with semisymmetric metric connection. We derive the curvatures formulas for doubly warped product manifold with semi-sym…
Warped products with a Tripathi connection
Abdoul Salam Diallo, Fortuné Massamba, Salomon Joseph Mbatakou
The warped product of two Riemannian manifolds and is the product manifold equipped with the warped product metric $g=g_…
On doubly twisted product immersions
Abdoul Salam Diallo, Fortuné Massamba
Some basic geometric properties of doubly twisted product immersions are established.
