Anomalous exponents and RG for nonlinear diffusion equations
In this paper, we discuss how to combine Renormalization Group Methods (RG) and classical
PDE techniques to study nonlinear diffusion equations and systems with critical nonlinearity. In particular, we
demonstrate, using several examples, the successful application of RG, when sharp a priori estimates are
derived, in showing universal global dynamics involving anomalous exponents for nonlinear systems in $R^n$.
