DESCRIPTION:Title: <a href="https://researchseminars.org/talk/PSMQFT/3/">T
 he flow approach to SPDEs with boundary conditions</a>\nby Nikolay Barashk
 ov (Max Planck Institute\, Leipzig) as part of Probability\, Statistical M
 echanics and Quantum Fields\n\n\nAbstract\nWe will discuss how to study re
 normalisation of Stochastic PDEs in the presence of Boundary conditions\, 
 using the flow approach introduced by Pawel Duch. In particular we look at
  the $\\Phi^4$ equation with Dirichlet boundary conditions on a general do
 main with smooth boundary. We find the need for additional renormalisation
  accounting for the boundary conditions\, as in previous work of Gerencer 
 and Hairer. We show that this boundary renormalisation can be taken consta
 nt even for domains with curved boundary. This is joint work with Majdouli
 ne Borji and Leonard Ferdinand.\n
