Actions for Integrable Systems and Deformed Conformal Field Theories
Invited talk given at the NSERC-CAP Workshop
Quantum Groups, Integrable Models and Statistical Systems,
Kingston, Ontario (July 1992). Published in workshop proceedings (Plenum 1993).
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.
