GL(2,R) gauge theory of (1+1)-dimensional gravity

Abstract

We formulate a GL(2,R) gauge theory of (1+1)-dimensional gravity, which contains the Jackiw-Teitelboim model and the dilaton gravity model as special cases. A general classical solution of the theory is given, and it is shown that the solution reduces to those of the special cases when appropriate limits of parameters are taken. © 1993 The American Physical Society.
