Abstract
Renormalization Group was originally developed for the understanding of Critical Phenomena and continuum limit in Quantum Field Theory. We show how similair ideas turn out to be useful in the study of long time asymptotics of solutions of parabolic nonlinear or random Partial Differential Equations. We show how universality, i.e. independence of the asymptotics on initial data and the equation, emerges naturally. Concrete problems discussed include patterns and moving fronts in Ginzburg Landau equation and diffusion in random environment.
