On repellers in quasi-periodically forced logistic map system
Tsuyoshi Chawanya, Takafumi Sakai
We propose a method to identify and to locate "repellers'' in quasi-periodically forced logistic map (QPLM), using a kind of Morse decomposition of nested attracting invariant sets…
Collective motions in globally coupled tent maps with stochastic updating
Satoru Morita, Tsuyoshi Chawanya
We study a generalization of globally coupled maps, where the elements are updated with probability . When is below a threshold , the collective motion vanishes and the…
Noiseless Collective Motion out of Noisy Chaos
Tatsuo Shibata, Tsuyoshi Chawanya, Kunihiko Kaneko
We consider the effect of microscopic external noise on the collective motion of a globally coupled map in fully desynchronized states. Without the external noise a macroscopic var…
A New Type of Irregular Motion in a Class of Game Dynamics Systems
Tsuyoshi Chawanya
A new type of asymptotic behavior in a game dynamics system is discovered. The system exhibits behavior which combines chaotic motion and attraction to heteroclinic cycles; the tra…
Weakly Chaotic Population Dynamics in Random Ecological Networks
Shin-ichi Sasa, Tsuyoshi Chawanya
Population dynamics in random ecological networks are investigated by analyzing a simple deterministic equation. It is found that a sequence of abrupt changes of populations punctu…
