Strong solutions to the stochastic quantization equations

Giuseppe Da Prato and Arnaud Debussche

Full-text: Open access


We prove the existence and uniqueness of a strong solution of the stochastic quantization equation in dimension 2 for almost all initial data with respect to the invariant measure. The method is based on a fixed point result in suitable Besov spaces.
