2D Induced Gravity as an Effective WZNW System
arXiv:hep-th/9804197 · doi:10.1103/PhysRevD.58.084024
Abstract
We introduced a dynamical system given by a difference of two simple SL(2,R) WZNW actions in 2D, and defined the related gauge theory in a consistent way. It is shown that gauge symmetry can be fixed in such a way that, after integrating out some dynamical variables in the functional integral, one obtains the induced gravity action.
