A deterministic displacement theorem for Poisson processes. (English) Zbl 0887.58018

Summary: We announce a deterministic analog of Bartlett’s displacement theorem. The result is that a Poisson property is stable with respect to deterministic Hamiltonian displacements. While the random point configurations move according to an \(n\)-body evolution, the mean measure \(P\) satisfies a nonlinear Vlasov type equation \[ \dot{P} + y \cdot \nabla_x P - \nabla_y \cdot E(P) = 0. \] Combined with Bartlett’s theorem, the result generalizes to interacting Brownian particles, where the mean measure satisfies a McKean-Vlasov type diffusion equation \[ \dot{P} + y \cdot \nabla_x P-\nabla_y \cdot E(P)- c \Delta P=0. \]
