| Popis: | In the context of the stochastic quantization we propose factorized approximate solutions for the Fokker-Planck equation for the XY and ZN spin systems in D dimensions. The resulting differential equation for a factor can be solved and it is found to give in the limit of t→∞ the mean field or, in the more general case, the Bethe-Peierls approximation. |
