Abstract

The authors investigate the applicability of the real-space renormalisation group technique to the directed percolation problem in two dimensions. They formulate decimation transformations that take into account the existence of two length scales in the problem. It is found that the values of critical parameters obtained are unreliable, as different approximate renormalisations give widely differing values.
