J. Freund et al., SELF-SIMILAR SEQUENCES AND UNIVERSAL SCALING OF DYNAMICAL ENTROPIES, Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 54(5), 1996, pp. 5561-5566
Symbol sequences play a prominent role in the context of symbolic dyna
mics. Important features of a dynamical system are reflected by relate
d statistics of subsequences. A dynamical behavior giving rise to a se
lf-similar attractor and universal scaling relations, expressed by cri
tical exponents, will lead to self-similar statistics of subsequences.
In the present paper we show how self-similar distributions of subseq
uences, i.e., temporal self-similarity, can be connected with a scalin
g relation for dynamical entropies. Moreover, the effect of slightly p
erturbing perfectly self-similar sequences by contaminating them with
noise is investigated. The achieved results are of importance for phys
ical processes marking the borderline between order and chaos.
