Abstract
It is shown that Liouville theory can be regarded as an SL(2, R) Wess-Zumino-Novikov-Witten theory with conformal invariant constraints and that Polyakov’s SL(2, R) Kac-Moody symmetry of induced two-dimensional gravity is just one side of the WZNW current algebra. Analogously, Toda field theories can be regarded as conformal-invariantly constrained WZNW theories for appropriate (maximally noncompact) groups.
