Dominant collective motion in globally coupled tent maps
نویسندگان
چکیده
We investigate collective motion in high dimensional chaos, where all elements in a population behaves chaotically and incoherently in appearance. Numerical experiments for globally coupled tent maps show the existence of a quasi-periodic collective motion even under slight interaction. It is found that the amplitude of the collective motion F is scaled as, KF ∝ exp(−K−1), by the coupling strength K. The collective motion is qualitatively equivalent over a parameter range of O(KF ) in the tent map. The phase diagram for the collective motion is studied in detail from a viewpoint of the dominant collective motion. 05.45+b 05.90+m Typeset using REVTEX

Collective motions in globally coupled tent maps with stochastic updating.
We study a generalization of globally coupled maps, where the elements are updated with probability p. When p is below a threshold p(c), the collective motion vanishes and the system is the stationary state in the large size limit. We present the linear stability analysis.
متن کاملOn the Collective Motion in Globally Coupled Chaotic Systems
A mean–field formulation is used to investigate the bifurcation diagram for globally coupled tent maps by means of an analytical approach. It is shown that the period doubling sequence of the single site map induces a continuous family of periodic states in the coupled system. This type of collective motion breaks the ergodicity of the coupled map lattice. The stability analysis suggests that t...
متن کاملBifurcations in Globally Coupled Chaotic Maps
We propose a new method to investigate collective behavior in a network of globally coupled chaotic elements generated by a tent map. In the limit of large system size, the dynamics is described with the nonlinear FrobeniusPerron equation. This equation can be transformed into a simple form by making use of the piecewise linear nature of the individual map. Our method is applied successfully to...
متن کاملRemarks on the mean field dynamics of networks of chaotic elements
Fluctuations of the mean field of a globally coupled dynamical systems are discussed. The origin of hidden coherence is related with the instability of the fixed point solution of the self-consistent Perron-Frobenius equation. Collective dynamics in globally coupled tent maps are re-examined, both with the help of direct simulation and the Perron-Frobenius equation. Collective chaos in a single...
متن کاملGlobal Analysis of Synchronization in Coupled Maps
We introduce a new method for determining the global stability of synchronization in systems of coupled identical maps. The method is based on the study of invariant measures. Besides the simplest non-trivial example, namely two symmetrically coupled tent maps, we also treat the case of two asymmetrically coupled tent maps as well as a globally coupled network. Our main result is the identifica...
