Abstract:
In this work we have obtained the set of new exact solutions of Einstein
equations that generalize the known LTB solution for the particular case
of nonzero pressure under zero spatial curvature. These solutions are
pretending to describe the black hole immersed in nonstatic cosmological
background and give a possibility to investigate the hot problems
concerning the effects of the cosmological expansion in gravitationally
bounded systems and other related problems. It was shown that each of
the solutions obtained contains either the Reissner-Nordstrom or the
Schwarzschild black hole in the central region of the space. It is
demonstrated that the approach of the mass function use in solving the
Einstein equations allows clear physical interpretation of the resulting
solutions that is of much benefit to any their concrete application.
