Renormalization of Generalized KPZ equation

Abstract

We use Renormalization Group to prove local well posedness for a generalized KPZ equation introduced by H. Spohn in the context of stochastic hydrodynamics. The equation requires the addition of counter terms diverging with a cutoff $\epsilon$ as ${\epsilon }^{-1}$ and $\log {\epsilon }^{-1}$.
