Late-time tails, entropy aspects, and stability of black holes with anisotropic fluids
B. Cuadros-Melgar, R. D. B. Fontana, Jeferson de Oliveira
In this work we consider black holes surrounded by anisotropic fluids in four dimensions. We first study the causal structure of these solutions showing some similarities and diffe…
