Abstract: | We investigate the expanding and collapsing regions by taking two well-known spherically symmetric spacetimes. For this purpose,
the general formalism is developed by using Israel junction conditions for arbitrary spacetimes. This has been used to obtain
the surface energy density and the tangential pressure. The minimal pressure provides the gateway to explore the expanding
and collapsing regions. We take Minkowski and Kantowski-Sachs spacetimes and use the general formulation to investigate the
expanding and collapsing regions of the shell. |
