摘要
We report a new family of solutions to Einstein-Maxwell-dilaton gravity in 2 + 1 dimensions and Einstein-Maxwell gravity with cylindrical symmetry in 3 + 1 dimensions. A set of static charged solutions in 2 + 1 dimensions are obtained by a compactification of charged solutions in 3 + 1 dimensions with cylindrical symmetry. These solutions contain naked singularities for certain values of the parameters considered. New rotating charged solutions in 2 + 1 dimensions and 3 + 1 dimensions are generated treating the static charged solutions as seed metrics and performing SL(2; R) transformations.
