摘要:

该文讨论一阶格点系统的解在相空间中的概率分布问题.作者先证明该格点系统的解算子生成的过程存在拉回吸引子,然后证明拉回吸引子上存在唯一的Borel不变概率测度,且该不变测度满足Liouville型方程.

关键词: 格点系统, 拉回吸引子, 不变测度, Liouville型方程

Abstract:

This article discusses the probability distribution of solutions in the phase space for the first-order lattice system. The authors first prove the the process generated by the solutions operator of the lattice system possesses a pullback attractor. Then they prove that there is a unique family of invariant probability measures contained in pullback attractor and the measures satisfy a Liouville type equation.

Key words: Lattice system, Pullback attractor, Invariant measure, Liouville type equation
