Gravitational collapse and the cosmological constant

摘要: We consider here the effects of a nonvanishing cosmological term on final fate spherical inhomogeneous collapsing dust cloud. It is shown that, depending nature initial data from which collapse evolves, and for positive value constant, we can have globally regular evolution where bounce develops within characterize precisely causing such in terms density velocity profiles In cases otherwise, result either formation black hole or naked singularity resulting as end state collapse. also show that cover part spectrum visible corresponding models same data.
