当单个自旋的态数足够大时，我们证明了v≧2的v维Potts模型中存在一级相变。实验证明，低温纯相可以存活到临界温度以下。当基础规范群有限但很大时，也得到了v维Potts规范模型v≧3的一阶跃迁的存在性。
We show the existence of a first-order phase transition in thev-dimensional Potts model forv≧2, when the number of states of a single spin is big enough. Low-temperature pure phases are proved to survive up to the critical temperature. Also the existence of a first-order transition in thev-dimensional Potts gauge model,v≧3, is obtained if the underlying gauge group is finite but large.
