ガウス型白色雑音によるミンコフスキー時空での確立過程量子化

その他

　We have proposed stochastic quantization procedure in Minkowski space-time in previous papers. That formulation , however, was done with non-Gaussian white noises. In this article we show that the equivalent formulation is possible with Gaussian white noises. This will be useful for the application to numerical analysis though manifest covariance of the theory under Lorentz transformation is lost. The covariance is restored at the Green function level.
