流动与铁磁体

Flows and ferromagnets

Geoffrey Grimmett

摘要:

图$G$上的Potts模型的两点相关函数可以用从$G$导出的“泊松"随机图的流多项式来表示,通过用其自身的泊松分布副本数替换每条边。这一事实将所谓的伊辛模型的随机电流展开扩展到波茨模型。

英文摘要:

The two-point correlation function of a Potts model on a graph $G$ may be expressed in terms of the flow polynomials of `Poissonian' random graphs derived from $G$ by replacing each edge by a Poisson-distributed number of copies of itself. This fact extends to Potts models the so-called random-current expansion of the Ising model.
