We consider an operatorK˚ϕ =Lϕ−: <CDU(x),Dϕ> in a Hilbert spaceH, whereLis an Ornstein–Uhlenbeck operator,U∈W1,4(H, μ) and μ is the invariant measure associated withL. We show thatK˚is essentially self-adjoint in the spaceL2(H, ν) where ν is the “Gibbs” measure ν(dx) =Z−:1e−:2U(x)dx. An application to Stochastic quantization is given.
