抛物型随机偏微分方程的重正化

Renormalisation of parabolic stochastic PDEs

Martin Hairer

摘要:

我们给出了一个调查的最新结果,从统计力学的系统的标度极限,以及在所谓的交叉制度,这样的系统的行为的普遍性。它透露,这些泛对象的描述奇异随机偏微分方程。然后,我们给出了一个调查最近开发的理论的规律性结构,允许建立这些对象,并描述它们的一些属性。我们特别强调的重正化过程中需要赋予这些方程的意义。以下是2017年11月4日在东京大学举行的第20次高木讲座的扩展笔记。

英文摘要:

We give a survey of recent result regarding scaling limits of systems from statistical mechanics, as well as the universality of the behaviour of such systems in so-called cross-over regimes. It transpires that some of these universal objects are described by singular stochastic PDEs. We then give a survey of the recently developed theory of regularity structures which allows to build these objects and to describe some of their properties. We place particular emphasis on the renormalisation procedure required to give meaning to these equations. These are expanded notes of the 20th Takagi lectures held at Tokyo University on November 4, 2017.
