杨振宁学术成就——量子不可积相位因子和规范场的积分表示

ANOTHER GREAT ACHIEVEMENT OF C.N.YANG——THE QUANTUM NON-INTEGRABLE PHASE FACTOR AND GLOBAL FORMALISM FOR GAUGE FIELD

摘要: 简要介绍杨振宁的一项重要学术贡献.一般物理学界人士都熟悉杨振宁在现代物理学中的三项伟大贡献：（1）非阿贝尔规范场理论；（2）杨-Baxter方程；（3）弱互作用宇称不守恒.文章介绍的是在这三大贡献之外的一项较少为人知的重要贡献：量子不可积相位因子和规范场的积分表示.

Abstract: It is well-known that C.N.Yang made three great contributions to modern physics. Another of his important contributions is less known but not less important ——the quantum non-integrable phase factor and global formalism for gauge fields.
