We study the porous medium equation with sign changes and examine the way sign changes disappear. We give a formal classification of self-similar and non-self-similar 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.
