-function of the level-zero Gross-Neveu model
Dmitri Bykov
We explain that the supersymmetric sigma model is directly related to the level-zero chiral Gross-Neveu (cGN) model. In particular, beta functions of the two theories sh…

Integrable sigma models on Riemann surfaces
Dmitri Bykov
We consider quantum aspects of a class of generalized Gross-Neveu models, which in special cases reduce to sigma models. We show that, in the case of gauged models, an admissible g…
