Renormalization group equations for a two-dimensional nonlinear sigma-model with torsion

The renormalization group equations in the one-loop approximation are formulated for a two-dimensional nonlinear -model with torsion on a semisimple group manifold. Solutions of these equations are investigated for several particular cases.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 9, pp. 37–40, September, 1988.
