三柱Hanoi塔图的谱

Spectra of three-peg Hanoi towers graphs

Brett Hungar, Gamal Mograby, Madison Phelps, Luke G. Rogers, Jonathan Wheeler

摘要:

我们考虑了两个序列的可平面图上的拉普拉斯算子之间的关系,一个来自自相似群理论,一个来自分形分析。通过在这些序列之间建立一个谱抽取映射,我们给出了前者谱的一个初等计算,这是由Grigorchuk和Šunić首先计算的。我们的方法也给出了本征函数的完整描述。

英文摘要:

We consider the relationship between the Laplacians on two sequences of planar graphs, one from the theory of self-similar groups and one from analysis on fractals. By establishing a spectral decimation map between these sequences we give an elementary calculation of the spectrum of the former, which was first computed by Grigorchuk and Šunić. Our method also gives a full description of the eigenfunctions.
