Diaz-Guilera described in an impressive letter how one can perform the renormalization group analysis in the presence of the singular Heaviside step function [CITE]. The latter enters inevitably when one derives coarse-grained Langevin equations for the various cellular-automaton algorithms arising in the study of self-organized criticality [CITE], [CITE].
