Diagram expansions in classical stochastic field theory
arXiv:cond-mat/9712192
Abstract
A diagram approach to classical nonlinear stochastic field theory is introduced. This approach is intended to serve as a link between quantum and classical field theories, resulting in an independent constructive characterisation of the measure in Feynman path integrals in terms of stochastic differential equations for the paths.
