| Popis: | In this paper we study the accretion of dark energy onto a black hole in the cases that dark energy is equipped with a positive cosmological constant and when the space-time is described by a Schwarzschild-de Sitter metric. While the first case is the same as the usual accretion procedure for a more complicated fluid, the second one give rise to a consistent cosmic scenario for the mentioned phenomenon. © Springer Science+Business Media, LLC 2009.
