确定自仿射分块的纯尖性的算法
Algorithm for determining pure pointedness of self-affine tilings
摘要:
$\R^d$中自仿射镶嵌的重叠重合等价于镶嵌动力系统的纯点动力学谱。我们解释了$\R^d$中置换Delone集的重叠重合性,并找到了一个检验纯点动力学谱的有效算法。该算法易于实现为计算机程序。我们给出的程序,并将其应用到几个例子。在算法的证明过程中,我们给出了Urbaidski(Solomyak \cite{Solomyak:08})关于分形瓦片边界的豪斯多夫维数的猜想的一个变形.
英文摘要:
Overlap coincidence in a self-affine tiling in $\R^d$ is equivalent to pure point dynamical spectrum of the tiling dynamical system. We interpret the overlap coincidence in the setting of substitution Delone set in $\R^d$ and find an efficient algorithm to check the pure point dynamical spectrum. This algorithm is easy to implement into a computer program. We give the program and apply it to several examples. In the course the proof of the algorithm, we show a variant of the conjecture of Urbański (Solomyak \cite{Solomyak:08}) on the Hausdorff dimension of the boundaries of fractal tiles.
