Path integral approach to bosonization of D=2 field theories
arXiv:hep-th/9501139 · doi:10.1007/s002880050235
Abstract
We suggest a method of bosonizing any D=2 theory. We demonstrate how it works with the examples of the Thirring and the Schwinger models, known results are reproduced. This method, being applied to the Gross-Neveu model, yields nonlinear boson WZW-type theory with additional constraint in the field space. Relation to the nonlinear sigma - model is also discussed.
