摘要：

Gravity coupled to a scalar field in two dimensions is studied and it is shown that in the light-cone gauge there exists a new symmetry associated with the scalar field that leads naturally to the SL(2,R) Kač-Moody current algebra. This algebra is derived from the traceless part of the energy-momentum tensor whose conservation is shown to give the well-known constraint necessary to obtain the chiral SL(2,R) algebra. © 1990.
