摘要
A class of perturbatively charged rotating dilaton black hole solutions coupled to the nonlinear BornInfeld electrodynamics is presented. The strategy for obtaining these solutions is to start from Myers-Perry solutions and then, considering the effects of the dilaton field, Born-Infeld parameter as well as the electric charge as a perturbative parameter. We perform the perturbations up to fourth order in the extremal black holes of Einstein-Born-Infeld-dilaton gravity with two equal angular momenta and arbitrary dilaton coupling constant. We discuss the physical properties of these black holes and study their dependence on the perturbative parameter q, the dilaton coupling constant a, and the Born-Infeld parameter beta. One can see these black holes solutions satisfy a generalized Smarr relation.
