随机微分方程和无限时域倒向微分方程的平稳解

Stationary Solutions of SPDEs and Infinite Horizon BDSDEs

Qi Zhang, Huaizhong Zhao

摘要:

本文研究随机偏微分方程平稳解的存在性。建立了无穷水平上倒向双随机微分方程的$L_ρ^2({\mathbb{R}^{d}};{\mathbb{R}^{1}}) \otimes L_ρ^2({\mathbb{R}^{d}};{\mathbb{R}^{d}})$值解与随机微分方程定常解之间的一种新的联系.此外,我们还证明了BDSDEs在有限和无限水平上解的存在唯一性,从而得到了SPDEs的初值问题的解和平稳解(与任何初值无关). SPDE和BSDES的弱解的联系在SPDE和BSDES的领域中具有独立的利益。

英文摘要:

In this paper we study the existence of stationary solutions for stochastic partial differential equations. We establish a new connection between $L_ρ^2({\mathbb{R}^{d}};{\mathbb{R}^{1}}) \otimes L_ρ^2({\mathbb{R}^{d}};{\mathbb{R}^{d}})$ valued solutions of backward doubly stochastic differential equations (BDSDEs) on infinite horizon and the stationary solutions of the SPDEs. Moreover, we prove the existence and uniqueness of the solutions of BDSDEs on both finite and infinite horizons, so obtain the solutions of initial value problems and the stationary solutions (independent of any initial value) of SPDEs. The connection of the weak solutions of SPDEs and BDSDEs has independent interests in the areas of both SPDEs and BSDEs.
