一类分段仿射映射的匹配

Matching in a family of piecewise affine maps

Henk Bruin, Carlo Carminati, Stefano Marmi, Alessandro Profeti

摘要:

考虑了一类单参数区间映射族,并研究了度量(分别为)拓扑)熵随着参数的变化而变化。我们表明,在许多情况下,熵显示半正规的行为,即它是光滑的开放和密集集。这个特征是由于一种叫做匹配的组合属性

英文摘要:

We consider a class of simple one parameter families of interval maps, and we study how metric (resp. topological) entropy changes as the parameter varies. We show that in many cases the entropy displays a semi-regular behaviour, i.e. it is smooth on an open and dense set. This feature is due to a combinatorial property called matching
