GLOBAL WELL-POSEDNESS OF THE DYNAMIC 4 MODEL IN THE PLANE

We show global well-posedness of the dynamic Φ4 model in the plane. The model is a non-linear stochastic PDE that can only be interpreted in a “renormalised” sense. Solutions take values in suitable weighted Besov spaces of negative regularity. MSC 2010: 81T27, 81T40, 60H15, 35K55.
