Solutions for Two-Dimensional Dilaton Gravity

In a recent paper Frolov, Hendy, and Larsen(1996) obtained a set of two nonlinear second-ordercoupled partial differential equations of 2D dilatongravity. They obtained a special solution assuming all the dependent variables were independent oftime. In the present work we reduce the above set ofequations to a simple form, from which we obtain a classof solutions that includes the solution of Frolov, Hendy, and Larsen as a special case.
