TL;DR: In this paper, the authors investigate statistical operators and an entropy functional for Bernstein stochastic processes associated with hierarchies of forward-backward systems of decoupled deterministic linear parabolic partial di¤erential equations.
Abstract: In this article we de…ne and investigate statistical operators and an entropy functional for Bernstein stochastic processes associated with hierarchies of forward-backward systems of decoupled deterministic linear parabolic partial di¤erential equations. The systems under consideration are de…ned on open bounded domains D R d of Euclidean space where d 2 N + is arbitrary, and are subject to Neumann boundary conditions. We assume that the elliptic part of the parabolic operator in the equations is a self-adjoint Schrodinger operator, bounded from below and with compact resolvent in L 2 (D). The statistical operators we consider are then trace-class operators de…ned from sequences of probabilities associated with the point spectrum of the elliptic part in question, which allow the distinction between pure and mixed processes. We prove in particular that the Bernstein processes of maximal entropy are those for which the associated sequences of probabilities are of Gibbs type. We illustrate our results by considering processes associated with a speci…c hierarchy of forward-backward heat equations de…ned in a two-dimensional disk.
