Global properties of charged dilatonic Gauss-Bonnet black holes

Global properties of charged dilatonic Gauss-Bonnet black holes

We study the phase space of the spherically symmetric solutions of Einstein-Maxwell-Gauss-Bonnet system nonminimally coupled to a scalar field and prove the existence of solutions with unusual asymptotics in addition to asymptotically flat ones. We also find new dyonic solutions of dilatonic Einstein-Maxwell theory.
