Dr Yvain Bruned from the University of Edinburgh will be presenting this seminar.
In this talk, we consider the fractional $\Phi^3_d$ model which is a stochastic PDEs on the d-dimensional torus with fractional Laplacian and quadratic nonlinearity driven by space-time white noise. We obtain precise asymptotics on the renormalisation counterterms as the mollification parameter becomes small and the parameter of the fractional Laplacian approaches its critical value. This is a joint work with Nils Berglund.
