An exploration of the curvature and inheritance properties of the Interior black hole spacetime
Absos Ali Shaikh, Kamiruzzaman
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.…
