Resumen:
We present a review of the pseudo-complex General Relativity, which is
an algebraical extension of the standard theory. In the Einstein
equations a new contribution arises, which is related to vacuum
fluctuations building up near large masses. Though the theory is richer
in structure, as it includes a minimal length, here we will neglect this
minimal length and concentrate on the effects of the presence of dark
energy. Stable circular orbits and the redshift are considered and
compared to some observational data. Finally, accretion disks are
simulated, using the model of Page and Thorne from 1974, with the metric
adjusted to the new one. We want to convince that the model presented is
a very effective manner to include quantum effects on the
phenomenological level, i.e., it takes into account that mass not only
curves the space but also changes the vacuum properties, not taken into
account properly up to now.
