On the non-equilibrium states of the crystal lattice

Abstract:

We consider the Cauchy problem for an infinite crystal lattice in Z^{d}, d ≥ 1, with random initial data. We study the behavior of the distributions of the solutions as t → ∞.
The main goal is to find the limiting stationary non-equilibrium states in which there is a constant non-zero heat flux passing through the lattice.
