Abstract: Also available as Leiden preprint W98-20 (1998).
We study the porous medium equation with sign changes and
examine the way sign changes disappear. We give a formal
classification of selfsimilar and non-selfsimilar scenarios
for their disappearance, for N>1 restricting attention to
the radial case. The results we present on the
classification of similarity solutions are rigorous except
where indicated otherwise.
