The generalized Fenyes-Nelson model for free scalar field theory [PDF]
, 2002 The generalized Fenyes--Nelson model of quantum mechanics is applied to the free scalar field. The resulting Markov field is equivalent to the Euclidean Markov field with the times scaled by a common factor which depends on the diffusion parameter.
