Rössler模型中的同宿混沌

Homoclinic chaos in the Rössler model

Semyon Malykh, Yuliya Bakhanov, Alexey Kazakov, Krishna Pusuluri, Andrey L. Shilnikov

摘要:

研究了O.罗斯勒在1976年。我们特别感兴趣的是希尼科夫鞍焦点的回旋分叉,以及它们的协同作用如何决定模型的全局展开,以及其混沌吸引子的变换。我们采用两种计算方法,一维返回映射和专门为这个模型量身定制的符号方法,来仔细检查同宿分岔,以及检测Rössler模型的参数空间中的结构稳定和混沌动力学区域。

英文摘要:

We study the origin of homoclinic chaos in the classical 3D model proposed by O. Rössler in 1976. Of our particular interest are the convoluted bifurcations of the Shilnikov saddle-foci and how their synergy determines the global unfolding of the model, along with transformations of its chaotic attractors. We apply two computational methods proposed, 1D return maps and a symbolic approach specifically tailored to this model, to scrutinize homoclinic bifurcations, as well as to detect the regions of structurally stable and chaotic dynamics in the parameter space of the Rössler model.
