wand情形下三态硬心模型的周期Gibbs测度

Periodic Gibbs measures for three-state hard-core models in the case Wand

R. M. Khakimov, K. O. Umirzakova

AI总结:

本文研究Cayley树上三态HC模型的wand情形,求出两周期Gibbs测度不唯一的精确临界活度值,并分析二阶树上这些测度的极值性。

摘要:

我们考虑Cayley树上活度参数为$λ>0$的fertile三态Hard-Core(HC,硬心)模型。已知此类模型存在四种类型:wrench、wand、hinge和pipe。这些模型作为具有最近邻排斥的损失网络的简单例子而出现。在阶数$k\geq2$的Cayley树上的wand情形中,找到了使两周期Gibbs测度不唯一的精确临界值$λ>0$。此外,我们研究了二阶Cayley树上现有两周期Gibbs测度的极值性。

英文摘要:

We consider fertile three-state Hard-Core (HC) models with the activity parameter $λ>0$ on a Cayley tree. It is known that there exist four types of such models: wrench, wand, hinge, and pipe. These models arise as simple examples of loss networks with nearest-neighbor exclusion. In the case wand on a Cayley tree of order $k\geq2$, exact critical values $λ>0$ are found for which two-periodic Gibbs measures are not unique. Moreover, we study the extremality of the existing two-periodic Gibbs measures on a Cayley tree of order two.
