平稳Bratteli图上的不变测度

Invariant Measures on Stationary Bratteli Diagrams

S. Bezuglyi, J. Kwiatkowski, K. Medynets, B. Solomyak

摘要:

我们研究作用在定常(非简单)Bratteli图的道路空间上的动力系统。对于这样的系统,我们明确地描述了所有遍历概率测度不变的尾巴等价关系(或Vershik映射)。这些措施完全由图的关联矩阵描述。由于这样的图对应于替代动力系统,本说明书给出了一个算法,找到不变的概率测度的非周期性非最小替代系统。得到了这些结果的几个推论。特别地,我们证明了不变测度是不混合的,并给出了一个复数是Vershik映射的特征值的判据。

英文摘要:

We study dynamical systems acting on the path space of a stationary (non-simple) Bratteli diagram. For such systems we explicitly describe all ergodic probability measures invariant with respect to the tail equivalence relation (or the Vershik map). These measures are completely described by the incidence matrix of the diagram. Since such diagrams correspond to substitution dynamical systems, this description gives an algorithm for finding invariant probability measures for aperiodic non-minimal substitution systems. Several corollaries of these results are obtained. In particular, we show that the invariant measures are not mixing and give a criterion for a complex number to be an eigenvalue for the Vershik map.
