一类一般随机偏微分方程的解理论

A Solution Theory for a General Class of SPDEs

André Süß, Marcus Waurick

摘要:

本文将带乘性噪声的随机偏微分方程改写为\cite{picardbook}意义下的随机扰动发展方程,发展了确定性发展方程的通解理论.这使我们能够提出一个统一的解决方案理论的一般类的SPDE,我们相信有很大的潜力,进一步推广。我们将证明,许多标准的随机偏微分方程适合这一类以及许多其他SPDE,如随机麦克斯韦方程和时间分数随机偏微分方程的子域上的乘性噪声$\Rd$。该方法在精神上类似于\cite{dapratozabczyk}中的方法,但在不涉及群论并允许有效处理SPDE的耦合系统的意义上对其进行了补充。特别地,不需要存在(正则)基本解或格林函数。

英文摘要:

In this article we present a way of treating stochastic partial differential equations with multiplicative noise by rewriting them as stochastically perturbed evolutionary equations in the sense of \cite{picardbook}, where a general solution theory for deterministic evolutionary equations has been developed. This allows us to present a unified solution theory for a general class of SPDEs which we believe has great potential for further generalizations. We will show that many standard stochastic PDEs fit into this class as well as many other SPDEs such as the stochastic Maxwell equation and time-fractional stochastic PDEs with multiplicative noise on sub-domains of $\Rd$. The approach is in spirit similar to the approach in \cite{dapratozabczyk}, but complementing it in the sense that it does not involve semi-group theory and allows for an effective treatment of coupled systems of SPDEs. In particular, the existence of a (regular) fundamental solution or Green's function is not required.
