TOPOLOGICAL BLACK-HOLES IN WEYL CONFORMAL GRAVITY

We present a class of exact solutions of Weyl conformal gravity, which have an interpretation as topological black holes. Solutions with neg ative, zero or positive scalar curvature at infinity are found, the fo rmer generalizing the well known topological black holes in anti-de Si tter gravity. The rather delicate question of thermodynamic properties of such objects in Weyl conformal gravity is discussed; suggesting th at the thermodynamics of the solutions found should be treated within the framework of gravity as an induced phenomenon, in the spirit of Sa kharov's work.
