Abstract:
The third Poisson structure of KdV equation in terms of canonical “free fields” and reduced WZNW model is discussed. We prove that it is “diagonalized” in the Lagrange variables which were used before in formulation of 2d gravity. We propose a quantum path integral for KdV equation based on this representation.
