Gravitational collapse due to dark matter and dark energy in the braneworld scenario

摘要

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