Sur une généralisation de la notion de système dynamique de rang un définie par une propriété de pistage (On a weak version of the rank one property defined by shadowing)
摘要:
研究区间上分段单调映射的跟踪性质。它被证明是秩一性质的弱形式,秩一性质是抽象遍历论中的一个著名概念。我们表明,这一新的属性是隐含的有限,甚至当地的排名,但它是逻辑上独立的松散Bernoulliness。我们给出(反例),包括L.B.具有任意高阶多项式复杂度的系统。跟踪性质定义了所有零熵系统的一个小子集,在这个意义上,它定义了一个闭集,相对于$\db$ -度量,由汉明距离引起的内部是空的。我们也做了一些评论之间的联系的阴影系统和序列假设的阴影性质。
英文摘要:
We investigate a shadowing property which appears naturally in the study of piecewise monotonic maps of the interval. It turns out to be a weak form of the rank one property, a well-known notion in abstract ergodic theory. We show that this new property is implied by finite or even local rank, but that it is logically independent of loose Bernoulliness. We give (counter)examples, including L.B. systems with arbitrarily high-order polynomial complexity. The shadowing property defines a small subset of all zero-entropy systems, in the sense that it defines a closed set with empty interior with respect to the $\db$-metric, induced by the Hamming distance. We also make some remarks on the link between the shadowed system and the sequence assumed by the shadowing property.
