耦合映象中从同步到一次时滞动力学

From synchronous to one-time delayed dynamics in coupled maps

Celia Anteneodo, Juan Carlos Gonzalez-Avella, Raul O. Vallejos

摘要:

我们研究完全同步状态(CSS)的耦合逻辑映射系统作为三个参数的函数:相互作用强度($\varepsilon$),范围的相互作用($α$),可以从第一邻居的全球耦合,和一个参数($β$),允许连续扫描从非延迟到一次性延迟动态。我们在平面上识别出$α$ - $\varepsilon$周期轨道、极限环和混沌轨道,并描述了这些结构如何随时滞而变化。这些特征可以通过研究二维非时滞映射的分岔图得到解释。这使我们能够理解的影响,一次延迟的CSS,例如,正则化的混沌轨道和同步的短程耦合映射,观察时的动力学是适度延迟。最后,我们用三次和对数映射代替Logistic映射,以测试我们的发现的鲁棒性。

英文摘要:

We study the completely synchronized states (CSSs) of a system of coupled logistic maps as a function of three parameters: interaction strength ($\varepsilon$), range of the interaction ($α$), that can vary from first-neighbors to global coupling, and a parameter ($β$) that allows to scan continuously from non-delayed to one-time delayed dynamics. % We identify in the plane $α$-$\varepsilon$ periodic orbits, limit cycles and chaotic trajectories, and describe how these structures change with the delay. These features can be explained by studying the bifurcation diagrams of a two-dimensional non-delayed map. This allows us to understand the effects of one-time delays on CSSs, e.g, regularization of chaotic orbits and synchronization of short-range coupled maps, observed when the dynamics is moderately delayed. Finally, we substitute the logistic map by cubic and logarithmic maps, in order to test the robustness of our findings.
