Extremal Myers-Perry black holes in Born-Infeld-dilaton theory
  A class of perturbative charged rotating dilaton black hole solutions coupled to the nonlinear Born-Infeld 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 4th order in the extremal black holes of Einstein-Born-Infeld-dilaton gravity with equal angular momentum 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 $\alpha$ and the Born-Infeld parameter $\beta$. One can see these black holes solutions satisfy a generalized Smarr relation.
