DESCRIPTION:Title: <a href="https://researchseminars.org/talk/SPDEs/8/">Ma
 rtingale problems for some singular SPDEs</a>\nby Nicolas Perkowski (FU Be
 rlin) as part of Stochastic PDEs and their friends\n\n\nAbstract\nMost tec
 hniques for solving singular SPDEs\, such as regularity structures\, are b
 ased on pathwise calculus. It would be interesting to study singular SPDEs
  from a more probabilistic perspective\, for example via the martingale pr
 oblem. In general that is a too difficult problem at the moment\, but ther
 e are some equations for which we can do this. I will explain the ideas on
  the example of the conservative stochastic Burgers equation and indicate 
 how to extend the results to a larger class of equations that share a simi
 lar structure. A novelty of this approach is that it allows to prove (weak
 ) well-posedness for some scaling critical singular SPDEs. Based on works 
 with Massimiliano Gubinelli and Lukas Gräfner.\n
