Abstract

We consider a cosmological scenario in which the expansion of the Universe is dominated by phantom dark energy and black holes which condense out of the latter component. The mass of the black holes decreases via Hawking evaporation and by accretion of phantom fluid, but new black holes arise continuously, so that the overall evolution can be rather complex. We study the corresponding dynamical system to unravel this evolution and to single out scenarios where the Big Rip singularity does not occur. © Pleiades Publishing, Ltd., 2009.
