Gravitational collapse due to dark matter and dark energy in the brane world scenario

الأصل · EN

Gravitational collapse of FRW brane world embedded in a conformaly flat bulk is considered for matter cloud consists of dark matter and dark energy with equation of state p=ερ (ε<-1/3). The effect of dark matter and dark energy is being considered first separately and then a combination of them both with and without interaction. In some cases the collapse leads to black hole in some other cases naked singularity appears.
