A PANORAMA OF SINGULAR SPDES

Abstract

I will review the setting and some of the recent results in the field of singular stochastic partial differential equations (SSPDEs). Since Hairer’s invention of regularity structures this field has experienced a rapid development. SSPDEs are non-linear equations with random and irregular source terms which make them ill-posed in classical sense. Their study involves a tight interplay between stochastic analysis, analysis of PDEs (including paradifferential calculus) and algebra.
