具有局部Lipschitz系数的分布相关随机微分方程的长时间行为

Long-time behaviour for distribution dependent SDEs with local Lipschitz coefficients

Shan-Shan Hu

摘要:

通过引入局部Wasserstein距离,利用经典的截断变元,证明了具有局部Lipschitz系数的分布依赖型随机微分方程解的整体存在唯一性.由于测度依赖性,经典情形的点态条件可以简化为积分意义下的条件。在此适定性的基础上,利用测度相关的李雅普诺夫函数证明了系统的$r$阶矩指数稳定性,并在积分强单调条件下研究了不变概率测度的存在唯一性.最后给出了一些例子来说明本文的结果。

英文摘要:

By using a classical truncated argument and introducing the local Wasserstein distance, the global existence and uniqueness are proved for the distribution dependent SDEs with local Lipschitz coefficients. Due to the measure dependence, the conditions in the sense of pointwise for classical cases can be simplified to the conditions in the sense of integral. On the basis of the well-posedness, we prove the $r$-th moment exponential stability using the measure dependent Lyapunov functions and the existence and uniqueness of invariant probability measure is studied under the integrated strong monotonicity condition. Finally, some examples are given to illustrate the results in this paper.
