We analyze asymptotic scaling properties of a model class of anomalous
reaction-diffusion (ARD) equations. Numerical experiments show that solutions
to these have, for large t, well defined scaling properties. We suggest a
general framework to analyze asymptotic symmetry properties; this provides an
analytical explanation of the observed asymptotic scaling properties for the
considered ARD equations.Comment: To appear in J. Nonlin. Math. Phy
