Actions for Integrable Systems and Deformed Conformal Theories

Abstract

I report on work on a Lagrangian formulation for the simplest 1+1 dimensional integrable hierarchies. This formulation makes the relationship between conformal field theories and (quantized) 1+1 dimensional integrable hierarchies very clear.Comment: (based on a talk given at the NSERC-CAP Workshop, "Quantum Groups, Integrable Models and Statistical Systems", Kingston, Ontario, Canada, July 1992), 11 pages, plain tex, no figures, IASSNS-HEP-92/7
