Description
The effects of a minimal length on the Kerr metric are studied within a generalized metric theory, called the pseudo-complex General Relativity (pcGR), allowing for accumulation of dark energy around a star. The relevant parameters are the rotational Kerr parameter $a$ and the mass of a black hole, a parameter measuring the amount of dark energy accumulated. It is found that the metric is modified by a function factor, depending on $r$ and the minimal length $l$, implying a maximal acceleration. This factor shows several singularities. The corresponding effective potentials exhibit potential barriers, avoiding the increase of the black hole’s mass.
