D. J. Robinson, G. P. Morriss

摘要:

切动力学的李雅普诺夫模式和它们的动力学数值生成- { \it的数值动力学} -被认为是。我们提出了一个新的唯象描述的数值动力学结构,准确地再现了准一维硬盘系统的实验数据,并表明,李雅普诺夫模式的数值动力学是线性的,并从其余的切空间分离。此外,我们提出了一个新的,详细的结构的李雅普诺夫模式切线动力学,这意味着李雅普诺夫模式有明确的(在)稳定的时间方向。我们测试这个切线动力学和它的导数性质数值部分成功。唯象描述涉及的时间模式的线性组合的所有其他李雅普诺夫模式在同一极化分支和我们提出的李雅普诺夫模式切线动力学是基于零模式的切线动力学的形式。

英文摘要:

The tangent dynamics of the Lyapunov modes and their dynamics as generated numerically - {\it the numerical dynamics} - is considered. We present a new phenomenological description of the numerical dynamical structure that accurately reproduces the experimental data for the quasi-one-dimensional hard-disk system, and shows that the Lyapunov mode numerical dynamics is linear and separate from the rest of the tangent space. Moreover, we propose a new, detailed structure for the Lyapunov mode tangent dynamics, which implies that the Lyapunov modes have well-defined (in)stability in either direction of time. We test this tangent dynamics and its derivative properties numerically with partial success. The phenomenological description involves a time-modal linear combination of all other Lyapunov modes on the same polarization branch and our proposed Lyapunov mode tangent dynamics is based upon the form of the tangent dynamics for the zero modes.
