Free field representation for massive integrable models. (English) Zbl 0818.46079

Summary: A new approach to massive integrable models is considered. It allows one to find symmetry algebras which define the spaces of local operators and to get general representations for form-factors in the SU(2) Thirring and Sine-Gordon models.
