一类自相似Schreier图上Ising模型的分拆函数

Partition functions of the Ising model on some self-similar Schreier graphs

Daniele D'Angeli, Alfredo Donno, Tatiana Nagnibeda

摘要:

研究了三类收敛于无限自相似图的有限图上Ising模型的分拆函数和热力学极限。它们是由三个著名的实现为规则有根树的自同构群的群提供的:第一个Grigorchuk的中间生长群;复多项式$z^2-1$的迭代单值群,称为Basilica群;和Hanoi Towers群$H^{(3)}$,与谢尔宾斯基垫圈密切相关。

英文摘要:

We study partition functions and thermodynamic limits for the Ising model on three families of finite graphs converging to infinite self-similar graphs. They are provided by three well-known groups realized as automorphism groups of regular rooted trees: the first Grigorchuk's group of intermediate growth; the iterated monodromy group of the complex polynomial $z^2-1$ known as the Basilica group; and the Hanoi Towers group $H^{(3)}$ closely related to the Sierpinsky gasket.
