具有粒子-圆盘相互作用的开放系统的次指数混合

Sub-exponential mixing of open systems with particle-disk interactions

Tatiana Yarmola

摘要:

我们考虑一类机械粒子系统的确定性粒子-磁盘相互作用耦合到吉布斯热库在可能不同的温度。我们发现,存在一个独特的(非平衡)的稳定状态。该定态是混合的,而不是指数混合的,并且所有的初始分布都收敛于该定态,并且对于一类初始分布,收敛于定态的速度是次指数的.

英文摘要:

We consider a class of mechanical particle systems with deterministic particle-disk interactions coupled to Gibbs heat reservoirs at possibly different temperatures. We show that there exists a unique (non-equilibrium) steady state. This steady state is mixing, but not exponentially mixing, and all initial distributions converge to it. In addition, for a class of initial distributions, the rates of converge to the steady state are sub-exponential.
