In the literature we see that after introducing a geometric structure by imposing some
restrictions on Riemann–Christoffel curvature tensor, the same type structures given by …

The derivation-commutator R⋅CC⋅R of a semi-Riemannian manifold (M,g), \dimM≧4,
formed by its Riemann-Christoffel curvature tensor R and the Weyl conformal curvature …

In this paper, we investigate Pseudo-Z symmetric space-time manifolds. First, we deal with
elementary properties showing that the associated form A k is closed: in the case the Ricci …

In the literature, there are two different notions of pseudosymmetric manifolds, one by Chaki
[7] and other by Deszcz [16], and there are many papers related to these notions. The object …

We prove that warped product manifolds with p-dimensional base, p= 1, 2, satisfy some
pseudosymmetry type curvature conditions. These conditions are formed from the metric …

The objective of this article is to study topologically charged Eddington-inspired Born–Infeld
(briefly, EiBI) gravity spacetime. It is proved that the topologically charged EiBI spacetime …

In the literature of Riemannian geometry there are many conditions for the equivalency of
semisymmetric (resp., pseudosymmetric) and Ricci-semisymmetric (resp., Ricci …

In this paper, we analyze the relativistic and nonrelativistic energy spectra (fermionic Landau
levels) for the noncommutative quantum Hall effect with anomalous magnetic moment in the …

Abstract The Morris-Thorne wormhole is a spherically symmetric solution of Einstein field
equations with cosmological constant. The present article aims to investigate the geometric …

For any semi-Riemannian manifold (M, g) we define some generalized curvature tensor E as
a linear combination of Kulkarni-Nomizu products formed by the metric tensor, the Ricci …
