我们提出了一个纯粹的组合过程中找到一个孤立的邻居和一个指数对包含在一个给定的集合,是一个有限的联盟的立方体在Rs。它用于Hénon吸引子的孤立不变子集的Conley指数的计算机辅助计算。作为推论,证明了Hénon吸引子包含除3和5之外的所有主周期的周期轨道。
Synopsis We present a purely combinatorial procedure for finding an isolating neighbourhood and an index pair contained in a given set, being a finite union of cubes in Rs. It is applied for a computer-assisted computation of the Conley index of an isolated invariant subset of the Hénon attractor. As a corollary, it is shown that the Hénon attractor contains periodic orbits of all principal periods except for 3 and 5.
