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 prove that the Ricci tensor of an affine surface is skew-symmetric and nonzero everywhere if and only

In this paper, we study the doubly warped product manifolds with semi-symmetric metric connection. We derive the curvature formulas for doubly warped product manifold with semi-symmetric metric connection in terms of curvatures of components of doubl

The warped product $$M_1 \times _F M_2$$ of two Riemannian manifolds $$(M_1,g_1)$$ and $$(M_2,g_2)$$ is the product manifold $$M_1 \times M_2$$ equipped with the warped product metric $$g=g_1 + F^2 g_2$$ , where F is a positive function on $$M_1$$ .

In this paper, we study a class of minimal surfaces in the three-dimensional Lorentzian Walker manifolds. We proved the existence of minimal flat and non totally geodesic graphs on three dimensional Lorentzian Walker manifolds.

The Riemannian extension of torsion free affine manifolds $(M, \nabla)$ is an important method to produce pseudo-Riemannian manifolds. It is known that, if the manifold $(M, \nabla)$ is a torsion-free affine two-dimensional manifold with skew symmetr

In this paper, we study a new semi-symmetric non-metric connection. Firstly, we give its conjugate connection. After the generalized conjugate connection and the semi-conjugate connection of the semi-symmetric non-metric connection are also given. So
