INSTABILITY OF EQUILIBRIUM POSITIONS OF TWO-DIMENSIONAL KINETIC BROADWELL EQUATION. EXPONENTIAL STABILIZATION OF REGULAR PERIODIC EQUILIBRIUM POSITIONS
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.
