GLOBAL STRUCTURE OF 4D BLACK HOLE SOLUTIONS IN THE MODEL WITH ANISOTROPIC FLUID

We analyse the global causal structure of a family of four-dimensional sphericallysymmetric solutions with a horizon which appear in the model with 1-component anisotropic fluid. This family can be considered as a generalized analogs of the wellknown black hole solutions such as the Reissner-Nordstr¨om solution. The structure of regular horizons and singular boundaries is studied, and the corresponding Carter- Penrose diagrams are constructed for various values of the parameters of the model.
