THE GENERAL RELATIVITY IN HIGHER DIMENSION IS DESCRIBED BY THE GENERALIZED EINSTEIN-HILBERT ACTION

Аннотация

A black hole is one of the most fascinating object whose existence was predicted by general theory of relativity a century ago, as it can be described by the only three parameters: mass, angular momentum and charge, according to the nohair theorem. Its existence has recently been proven thanks to the technological development by the detected gravitational wave signals from coalescence of black holes/neutron stars in binary [1–6] by the LIGO-Virgo collaborations and by the observational evidence based on electromagnetic radiation coming from accretion disks around astrophysical black holes [7] as well as from the detected first ever image of the supermassive black hole at the center of the galaxy M87 by the Event we summarize main results obtained in the paper.
