New challenges in PDE: Deterministic dynamics and randomness in high and infinite dimensional systems October 19, 2015 - October 30, 2015

stochastic PDE-stochastic heat equation
35R15 - Partial differential equations on infinite-dimensional (e.g. function) spaces (= PDE in infinitely many variables) [See also 46Gxx, 58D25]
60B15 - Probability measures on groups or semigroups, Fourier transforms, factorization
We describe a general approach to the renormalisation step in the theory of regularity structures based on Hopf algebras of labelled trees (joint work with Yvain Bruned and Martin Hairer)."
