摘要

We study the stabilization rate of periodic perturbations of the equilibrium position for discrete kinetic equations in the model case of the two-dimensional Broadwell system. We propose a method for identifying a subset of periodic initial data for which the solution to the Cauchy problem for the Broadwell system with the corresponding periodic initial data (periodicperturbationsoftheequilibriumposition) exponentially stabilizes to equilibrium state.
