White holes in extended manifolds: The problem of existence

Global structure of the Kerr-Newman space-time manifold is considered. It consists of different regions — subluminal and superluminal, which are separated by pseudo-singular surfaces. Collapsing, anticollapsing, and oscillating motions are analyzed in such manifold, which correspond to black holes, white holes, and grey holes, respectively. Possibility of inner stability of the structure of space-time manifolds is shown as well as the removal of some difficulties of the white hole theory. Anticollapsars are divided into four types depending on the radius of maximal expansion.
