An exploration of the curvature and inheritance properties of the Interior black hole spacetime

Abstract

In continuation of the study in \cite{SDHK_interior_2020}, the present article explores the geometric and curvature properties of the interior black hole (briefly, IBH) spacetime. It is shown that in an IBH spacetime the operator $R\cdot C$ and $C\cdot R$ does not commute with each other and infact the commutator $C\cdot R-R\cdot C$ is linearly dependent with $Q(g,R)$ and $Q(S,R)$ as well as $Q(g,C)$ and $Q(S,C)$. Also in IBH spacetime $R\cdot R$ is linearly dependent with $Q(S,R)$ and $Q(g,C)$. It is exhibited that IBH spacetime is $2$-quasi Einstein, Ein$(2)$ and generalized quasi Einstein spacetime in the sense of Chaki, and its conformal $2$-forms are recurrent. We have derived the universal form of the compatible tensors in such a spacetime. We have also demonstrated that the nature of energy momentum tensor of IBH spacetime is pseudosymmetric (see, Theorem $4.1$). Again it is exposed that with respect to the non-Killing vector field $\frac{\partial }{\partial t},$ the IBH spacetime obeys the generalized curvature inheritance, generalized Ricci inheritance, special type of generalized conformal, concircular, conharmonic and generalized Weyl projective inheritance. Finally a comparison between IBH spacetime and KIselev Black Hole (KBH) is displayed.
