String Effective Action and Two-Dimensional Charged Black Hole
Abstract
Graviton-dilaton background field equations in three space-time dimensions, following from the string effective action are solved when the metric has only time dependence. By taking one of the two space dimensions as compact, our solution reproduces a recently discovered charged black hole solution in two space-time dimensions. Solutions in the presence of non-vanishing three-dimensional background antisymmetric tensor field are also discussed.
