β¦ Synopsis
We investigate the nonlinear diffusion equation βu/βt = u + u p p > 1 on certain unbounded fractal domains, where is the infinitesimal generator of the semigroup associated with a corresponding heat kernel. We show that there are nonnegative global solutions for non-negative initial data if p > 1 + 2/d s , while solutions blow up if p β€ 1 + 2/d s , where d s is the spectral dimension of the domain. We investigate smoothness and HΓΆlder continuity of solutions when they exist.

The method of generalized quasi-linearization has been well developed for ordinary differential equations. In this paper, we extend the method of generalized quasi-linearization to reaction diffusion equations on an unbounded domain. The iterates, which are solutions of linear equations starting fro
