Multidimensional black-hole solutions in models with an anisotropic fluid

Summary: "A family of black-hole solutions in the model with a 1-component anisotropic fluid is obtained. The metric of any solution contains n-1 Ricci-flat `internal space' metrics and for certain equations of state (p_i=pmrho) coincides with the metric of a black-brane (or black-hole) solution in a model with an antisymmetric form. Some examples (e.g., those simulating M2 and M5 black branes) are considered. The post-Newtonian parameters beta and gamma corresponding to the 4-dimensional section of the metric are calculated."
