本文运用严格重整化交换研究了三结点hierarchical晶格上具有三体相互作用的伊辛模型。研究表明,与布喇菲晶格上的情况一样,最近邻二体相互作用伊辛模型与三体相互作用伊辛模型(Baxter-Wu模型)属于不同的普适类。The critical behavior of Ising model with three-spin interactions on three-node hierarchical lattices is investigated by using an exact renormalization group transformation. As in the case of Bravais lattices, the model with two-spin interactions and the one with three-spin interactions belong to different universality classes.
