Abstract

This paper deals with the role of anisotropy and inhomogeneity of space–time in quasi-spherical gravitational collapse. The effect of the initial area radius has been studied in characterizing the final state of collapse. Both dust and fluid with anisotropic pressure are considered as the collapsing matter. The results are presented in the form of propositions.
