Ap. Kuznetsov et al., A VARIETY OF PERIOD-DOUBLING UNIVERSALITY CLASSES IN MULTIPARAMETER ANALYSIS OF TRANSITION TO CHAOS, Physica. D, 109(1-2), 1997, pp. 91-112
In multi-parameter analysis of the onset of chaos non-Feigenbaum perio
d-doubling behavior may occur at some special paths in the parameter s
pace. There are two possibilities: (i) the dynamics at the on rer of c
haos remains essentially one-dimensional, but the one-dimensional map
is distorted in such a way that leaves Feigenbaum's universality class
, (ii) a new mode comes to the threshold of instability and increases
the effective dimension of the dynamics. We submit a list of one-dimen
sional and two-dimensional maps which represent distinct classes of th
e period-doubling universality, discuss the properties of the associat
ed types of critical behavior at the border of chaos, and demonstrate
pictures of the universal parameter space arrangement near the critica
l points.
