I. Yekutieli et al., SELF-SIMILARITY OF THE BRANCHING STRUCTURE IN VERY LARGE DLA CLUSTERSAND OTHER BRANCHING FRACTALS, Journal of physics. A, mathematical and general, 27(2), 1994, pp. 275-284
We study the branching structure of very large DLA clusters, of up to
100 million particles. The Horton-Strahler ordering of the branches in
these clusters shows a relaxation towards a state with the stream num
bers forming a geometric series. This behaviour is compared with those
of several self-similar trees. It indicates that DLA clusters converg
e to topologically self-similar objects.
