Asymptotic analysis of a doubly nonlinear diffusion equation

We investigate the doubly nonlinear diffusion equation ∂u/∂t=1/n ∇.(u^m│∇u│^n-1) ∇u) and the same equation expressed in terms of a `pressure' variable. We classify various classes of compacted supported solutions, as well as finite-mass solutions that decay algebraically at infinity. A numbe...
