Non-asymptotically flat, non-dS/AdS dyonic black holes in dilaton gravity

We present exact spherically symmetric dyonic black hole solutions in fourdimensional and higher dimensional Einstein-Maxwell-dilaton gravity with Liouvilletype potentials for the dilaton field. These solutions have unusual asymptotics–they are neither asymptotically flat nor asymptotically (anti-) de Sitter. The solutions have one or two horizons hiding a curvature singularity at the origin. A class of topological dyonic black holes with topology of a torus is also presented in four dimensions. Some basic properties of the black holes are discussed.
