Abstract

The main objective of this paper is to prove the essential self-adjointness of Dirichlet operators in L2 (μ) where μ is a Gibbs measure on an infinite volume path space C (R, Rd). This operator can be regarded as a perturbation of the Ornstein-Uhlenbeck operator by a nonlinearity and corresponds to a parabolic stochastic partial differential equation (= SPDE, in abbreviation) on R. In view of quantum field theory, the solution of this SPDE is called a P (φ{symbol})1-time evolution.
