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…
