DESCRIPTION:TITLE: Singular Stochastic Partial Differential Equations - How
  do they arise and what do they mean?\n\nAbstract: Systems with random flu
 ctuations are ubiquitous in the real world. Stochastic PDEs are default mo
 dels for these random systems\, just as PDEs are default models for determ
 inistic systems. However\, a large class of such stochastic PDEs were poor
 ly understood until very recently: the presence of very singular random fo
 rcing as well as nonlinearities render it challenging to interpret what on
 e even means by a “solution”. The recent breakthroughs by M. Hairer\, M. G
 ubinelli and other researchers including the speaker not only established 
 solution theories for these singular SPDEs\, but also led to an explosion 
 of new questions. These include scaling limits of random microscopic model
 s\, development of numerical schemes\, ergodicity of random dynamical syst
 ems and a new approach to quantum field theory. In this talk we will discu
 ss the main ideas of the recent solution theories of singular SPDEs\, and 
 how these SPDEs arise as limits of various important physical models.\n
