Renato Calleja, Diego del-Castillo-Negrete, David Martinez-del-Rio, Arturo Olvera

摘要:

引入并研究了参数周期变化的标准映射的非自治形式。在变量和参数的映射的对称性发现,并用于找到之间的关系旋转数的不变集的自治实现的周期2的情况下的映射。研究了非自治动力学对周期轨道、稳定性和分岔的影响。用直接计算和延拓方法详细研究了全局输运的临界边界和固定旋转数不变圆的破坏。在整体输运的情况下,临界边界具有特殊的对称喇叭形状。结果与文献中发现的类似计算进行了对比。

英文摘要:

A non-autonomous version of the standard map with a periodic variation of the parameter is introduced and studied. Symmetry properties in the variables and parameters of the map are found and used to find relations between rotation numbers of invariant sets of the autonomous realization of the period-two case of the map. The role of the nonautonomous dynamics on period-one orbits, stability and bifurcation is studied. The critical boundaries for the global transport and the destruction of invariant circles with fixed rotation number are studied in detail using direct computation and a continuation method. In the case of global transport, the critical boundary has a particular symmetrical horn shape. The results are contrasted with similar calculations found in the literature.
