Hanoi型分形量子图的能量和Laplacian

Energy and Laplacian on Hanoi-type fractal quantum graphs

Patricia Alonso Ruiz, Daniel J. Kelleher, Alexander Teplyaev

摘要:

本文研究紧度量空间上的势理论和谱分析,我们称之为分形量子图。这些空间可以表示为一个(可能是无限的)1维区间和一个完全不连通(可能是不可数的)紧集的并集,它粗略地表示连接点的集合。经典的量子图和分形空间,如河内吸引子,其中包括。首先证明了Hanoi吸引子上的阻力形式的存在性,然后建立了Hanoi吸引子上的弱自相似测度对应的Laplacian特征值计数函数的热核估计和上下界.这些估计和边界严重依赖于分形的长度和体积缩放因子之间的关系。然后,我们陈述并证明了一般分形量子图上存在电阻形式的一个充分必要条件。最后,我们将我们的谱结果推广到一大类弱自相似分形量子图。

英文摘要:

This article studies potential theory and spectral analysis on compact metric spaces, which we refer to as fractal quantum graphs. These spaces can be represented as a (possibly infinite) union of 1-dimensional intervals and a totally disconnected (possibly uncountable) compact set, which roughly speaking represents the set of junction points. Classical quantum graphs and fractal spaces such as the Hanoi attractor are included among them. We begin with proving the existence of a resistance form on the Hanoi attractor, and go on to establish heat kernel estimates and upper and lower bounds on the eigenvalue counting function of Laplacians corresponding to weakly self-similar measures on the Hanoi attractor. These estimates and bounds rely heavily on the relation between the length and volume scaling factors of the fractal. We then state and prove a necessary and sufficient condition for the existence of a resistance form on a general fractal quantum graph. Finally, we extend our spectral results to a large class of weakly self-similar fractal quantum graphs.
