The dynamics of a symmetric coupling of three modified quadratic maps

引用

Chinese Physics B 2013年第8期22卷 233-237页

作者： paulo C. Rech Departamento de Física Universidade do Estado de Santa Catarina89219-710 Joinville Brazil

We investigate the dynamical behavior of a symmetric linear coupling of three quadratic maps with exponential terms, and identify various interesting features as a function of two control parameters. In particular, we investigate the emergence of quasiperiodic states arising from Naimark-Sacker bifurcations of stable period-l, period-2, and period-3 orbits. We also investigate the multistability in the same coupling. Lyapunov exponents, parameter planes, phase space portraits, and bifurcation diagrams are used to investigate transitions from periodic to quasiperiodic states, from quasiperiodic to mode-locked states and to chaotic states, and from chaotic to hyperchaotic states.

Some two-dimensional parameter-space diagrams are numerically obtained by considering the largest Lyapunov exponent for a four-dimensional thirteen-parameter Hindmarsh-Rose neuron *** different parameter planes are considered,and it is shown that depending on the combination of parameters,a typical scenario can be preserved:for some choice of two parameters,the parameter plane presents a comb-shaped chaotic region embedded in a large periodic *** is also shown that there exist regions close to these comb-shaped chaotic regions,separated by the comb teeth,organizing themselves in period-adding bifurcation cascades.

Let ACD（M, SL（d,R）） denote the pairs （f, A） so that f∈ A C Diff^1（M） is a C^1-Anosov transitive diffeomorphisms and A is an SL（d,R） cocycle dominated with respect to f. We prove that open and densely in ACD（M, SL（d,R））, in appropriate topologies, the pair （f,A） has simple spectrum with respect to the unique maximal entropy measure μf. Then, we prove prevalence of trivial spectrum near the dynamical cocycle of an area-preserving map and also for generic cocycles in AUtLeb（M） × LP（M, SL（d, R））.
