Infinite Quantum Group Symmetry in 2d Quantum Field Theory
arXiv:hep-th/9109020
Abstract
I describe how integrable quantum field theories in 2 spacetime dimensions are characterized by infinite dimensional quantum group symmetries, namely the q-deformations of affine Lie algebras, and their Yangian limit. These symmetries can provide a new non-perturbative formulation of the theories.
