From Stochastic Differential Equations to Quantum Field Theory

Abstract

Covariant stochastic partial (pseudo-)differential equations are studied in any dimension. In particular a large class of covariant interacting local quantum fields obeying the Morchio-Strocchi system of axioms for indefinite quantum field theory is constructed by solving the analysed equations. The associated random cosurface models are discussed and some elementary properties of them are outlined.Comment: 11 pages, Latex, to appear in: Reports On Mathematical Physics No.X Vol.XX (199X
