Pseudosymmetry and curvature inheritance of the interior black hole spacetime

Physics Letters B
The notion of pseudosymmetry by Adamów and Deszcz [1] generalizes the concept of local symmetry and semisymmetry, and it serves as a model of various spacetimes. The classification of pseudosymmetric spacetimes has been studied in [2].

Commuting Conditions of the k-th Cho operator with the structure Jacobi operator of real hypersurfaces in complex space forms

Open Mathematics, 2015
In this paper three dimensional real hypersurfaces in non-flat complex space forms whose k-th Cho operator with respect to the structure vector field ξ commutes with the structure Jacobi operator are classified.

Symmetry and pseudosymmetry properties with Ricci soliton of the Reissner-Nordström-de Sitter spacetime

Nuclear Physics B
The primary objective of the article is to investigate the symmetry and pseudosymmetry properties of the Reissner-Nordström-de Sitter (briefly, RNdS) spacetime. The secondary aim of the paper is to explore the notion of Ricci solitons in RNdS spacetimes.
