New class of rotating perfect fluid black holes in three dimensional gravity

Abstract

We obtain a new class of rotating black holes for Einstein theory with perfect fluid source in (Formula presented.) dimensions. We conclude that these black hole solutions only depend on the variable of the angular velocity (Formula presented.). Some examples of these black holes are given explicitly. In particular, an unknown static black hole in this special background is obtained. In addition, the general properties including the horizon structure, energy conditions and equation of state, mass, and angular momentum are explained in detail.
