Large N Limit on Langevin Equation: TwoDimensional Nonlinear Sigma Model
Abstract
We study the stochastic quantization of twodimensional nonlinear sigma model in the large $N$ limit. Our main tool is the {\it effective} Langevin equation with which we investigate nonperturbative phenomena and derive the results which are same as the path integral approach gives.
