Название: On the Asymptotic Behaviour of Spitzer's Model for Evolution of One-Dimensional Point Systems
Автор: Fritz J.
Journal of Statistical Physics, Vol. 38, Nos. 3/4, 1985. p. 615-645.
A nearest-neighbor gradient dynamics of one-dimensional infinite particle systems is considered; the model admits a two-parameter family of stationary configurations. Some domains of attraction of stationary configurations are described, and the continuum (hydrodynamical) limit of the system is investigated. It is shown that the mean density of points satisfies a nonlinear diffusion equation in the hydrodynamical limit.
