具组态噪声和非保守力的拟马尔可夫广义Langevin方程的遍历性

Ergodic properties of quasi-Markovian generalized Langevin equations with configuration dependent noise and non-conservative force

Benedict Leimkuhler, Matthias Sachs

摘要:

讨论了拟马尔可夫随机微分方程的遍历性,给出了在适当加权的$L^{\infty}$空间中保证光滑不变分布的存在唯一性和发展算子指数收敛的一般条件,从而证明了相应解过程的中心极限定理的有效性.主要的新结果是具有组态相关噪声和(非)保守力的广义Langevin方程的遍历性条件。

英文摘要:

We discuss the ergodic properties of quasi-Markovian stochastic differential equations, providing general conditions that ensure existence and uniqueness of a smooth invariant distribution and exponential convergence of the evolution operator in suitably weighted $L^{\infty}$ spaces, which implies the validity of central limit theorem for the respective solution processes. The main new result is an ergodicity condition for the generalized Langevin equation with configuration-dependent noise and (non-)conservative force.
