Renormalization Group Analysis of Nonlinear Diffusion Equations with Periodic Coefficients
Gastao A. Braga, Frederico Furtado, Jussara M. Moreira +1
In this paper we present an efficient numerical approach based on the Renormalization Group method for the computation of self-similar dynamics. The latter arise, for instance, as…

Renormalization Group Analysis of Nonlinear Diffusion Equations With Time Dependent Coefficients: Analytical Results
Gastão A. Braga, Frederico Furtado, Jussara M. Moreira +1
We study the long-time asymptotics of a certain class of nonlinear diffusion equations with time-dependent diffusion coefficients which arise, for instance, in the study of transpo…
