规范对称性与可积模型

Gauge Symmetry and Integrable Models

Hao-Shiung Lin, Oktay K. Pashaev, Shi-Shyr Roan

摘要:

建立了任意弯曲背景下的非线性$σ$模型与阿贝尔规范理论之间的同构关系,从而从规范理论的角度导出了可积模型和相应的Lax表示.在我们的方法中,谱参数与时空的共形变换或伽利略变换相关的整体自由度有关。B $\ddot{\rm a}$ cklund变换是从Chern-Simons理论导出的,其中谱参数是根据提取的紧化空间维坐标定义的。

英文摘要:

We establish the isomorphism between a nonlinear $σ$-model and the abelian gauge theory on an arbitrary curved background, which allows us to derive integrable models and the corresponding Lax representations from gauge theoretical point of view. In our approach the spectral parameter is related to the global degree of freedom associated with the conformal or Galileo transformations of the spacetime. The B$\ddot{\rm a}$cklund transformations are derived from Chern-Simons theory where the spectral parameter is defined in terms of the extract compactified space dimension coordinate.
