The Real-Space Renormalization Group Applied to Diffusion in Inhomogeneous Media
Mitsuhiro Kawasaki · arXiv (Cornell University) · 2002
The real-space renormalization group technique is introduced to evaluate the effective diffusion constant for diffusion in inhomogeneous media, which has been obtained by singular perturbation methods. Our method is formulated on a discretized real space and hence it can be easily combined with numerical studies for partial differential equations.
