چکیده

We present solution generating methods which allow us to construct exact static solutions to the equations of four-dimensional Einstein-MaxwellDilaton gravity starting with arbitrary static solutions to the pure vacuum Einstein equations, Einstein-dilaton or Einstein-Maxwell equations. In four dimensions the field equations of the Einstein-Maxwell-dilaton gravity with arbitrary dilaton coupling parameter α, can be obtained from the following Einstein frame action [1] A = − 1 16π ∫

Exact static solutions in four dimensional Einstein-Maxwell-Dilaton gravity

Classes of exact static solutions in four-dimensional Einstein-MaxwellDilaton gravity are found. Besides of the well-known solutions previously found in the literature, new solutions are presented.It’s shown that spherically symmetric solutions, except the case of charged dilaton black hole, represent globally naked strong curvature singularities. The scalar field is believed to play an importa...

We obtain the general static solutions of the axially symmetric (2+1)dimensional Einstein-Maxwell-Dilaton theory by dimensionally reducing it to a 2-dimensional dilaton gravity theory. The solutions consist of the magnetically charged sector and the electrically charged sector. We illuminate the relationship between the two sectors by pointing out the transformations between them. 04.20.jb, 04....

T – Duality and Spinning Solutions in 2 + 1 Gravity Chiang - Mei

Starting with the 2 + 1 Einstein–Maxwell–Dilaton system with a cosmological constant and assuming two commuting Killing symmetries we derive the corresponding 1 + 0 σ–model. It is shown that, for general values of the coupling parameters, the T –duality group is SL(2, R), which coincides with the group of linear coordinate transformations along the Killing orbits. This duality, along with a sui...
