R^(j(1/2))(x)的一般解与量子群结构

General Solutions of R^(j(1/2))(x) and Quantum Group Structure

从自旋J与1/2的统计模型出发,求得了R J(1/2)(x)的一般解,完成了杨-Baxterization方案,建立了相应量子群结构,并证明这种结构与标准量子群结构可以通过权守值加以确定,本文也讨论了这种不完整杨-Baxter方程对应的非标准量子群构造。

Starting from spin (j, 1/2) model we derive general solutions of associatedYang-Baxter equations. The corresponding structure of Quantum Group and the rela-tionship between it and the standard one are discussed. It is pointed out that thisincomplete Yang-Baxter system gives rise to a non-standard structure or QuantumGroup. The Yang-Baxterzation prescription for the model in carried out.
