摘要：
In this note we show that the induced 2D-gravity SL(2, R) currents can be defined in a gauge-independent way although they manifest themselves as generators of residual symmetries only in some special gauges. In the Coulomb gas representation we investigate two approaches, namely one resembling string field theory and another that emphasizes the SL(2, R) structure in the phase space. In the conformal gauge we propose a solution of the Liouville theory in terms of the SL(2, R) currents.
