Resumen:

General Relativity (GR) is algebraically extended to pseudo-complex (pc) coordinates. The new theory, called pc-GR, contains a minimal length and in addition requires the appearance of an energy-momentum tensor, related to the vacuum fluctuations (dark energy), provoked by the presence of the central mass. The dark energy density increases toward the central mass and avoids the appearance of an event horizon. Observational consequences are presented, related to Quasi-Periodic Oscillations in accretion disks around so-called galactic black holes, and the structure of these disks. © 2017 by World Scientific Publishing Co.
