Local renormalisation for singular SPDEs
In this talk, we will present the tools of regularity structures to deal with singular stochastic PDEs that involve non-translation invariant properties. We describe in particular the renormalised equation for a very large class of spacetime dependent renormalization schemes. Our approach is based on local renormalisation maps that act directly at the level of the equation. This is joint work with Ismael Bailleul.
