Non-axial self-similar hole filling for the porous medium equation

Author:

Angenent S.,Aronson D.

Abstract

We construct non-axially symmetric self-similar solutions to the porous medium equation by showing that the family of radial self-similar solutions found by Aronson and Graveleau (1993) undergoes a sequence of symmetry breaking bifurcations as the parameter m m decreases from m = m=\infty to m = 1 m=1 .
