Resumen de Global well-posedness of the dynamic Φ4Φ4 model in the plane

Jean-Christophe Mourrat, Hendrik Weber

• We show global well-posedness of the dynamic Φ4Φ4 model in the plane. The model is a nonlinear stochastic PDE that can only be interpreted in a “renormalised” sense. Solutions take values in suitable weighted Besov spaces of negative regularity.
