SUMMARY:The Critical 2d Stochastic Heat Flow and other critical SPDEs - Ni
 kos Zygouras (Warwick)
DTSTART:20240220T140000Z

DESCRIPTION:Thanks to the theories of  Regularity Structures\, Paracontrol
 led Distributions\nand Renormalisation we now have a robust framework for 
 singular SPDEs\, which are “sub-critical”\nin the sense of renormalisa
 tion. Recently\, there have been efforts to approach the situation\nof “
 critical” SPDEs and statistical mechanics models. A first such treatment
  has been\nthrough the study of the two-dimensional stochastic heat equati
 on\, which has revealed a\ncertain phase transition and has led to the con
 struction of the novel object called the\nCritical 2d Stochastic Heat Flow
 . In this talk we will present some aspects of this model\nand its constru
 ction. We will also present developments relating to other critical SPDEs.
 \nParts of this talk are based on joint works with Caravenna and Sun and o
 thers with Rosati and Gabriel.
