Z_2-reductions of spinor models in two dimensions

Abstract

We propose new types of integrable spinor models, generalizing the well known ones of: i) Nambu-Jona-Lasinio-Vaks-Larkin models, related to SU(N); ii) the Gross-Neveu models - SP(2N); and the iii) Zakharov-Mikhailov models - SO(N). We propose a method for constructing their Lax representation and outline the spectral properties of the Lax operators.
