杨-米尔斯理论中的Wong方程

Wong's equations in Yang-Mills theory

S. N. Storchak

摘要:

我们推导出了有限维动力系统的Wong方程,该动力系统代表了紧致黎曼流形上标量粒子的运动,具有紧致半单李群的自由等距光滑作用。所得到的方程是书面的依赖坐标,这是典型的使用在一个隐式描述的本地动态给出的轨道空间的主纤维束。利用这些方程,我们得到了库仑规范固定的纯杨-米尔斯规范理论中的Wong方程.这一结果是基于我们的有限维动力系统和杨-米尔斯规范场中进行的约化过程之间的现有类比。

英文摘要:

We derive Wong's equations for the finite-dimensional dynamical system representing the motion of a scalar particle on a compact Riemannian manifold with a given free isometric smooth action of a compact semisimple Lie group. The obtained equations are written in terms of dependent coordinates which are typically used in an implicit description of the local dynamics given on the orbit space of the principal fiber bundle. Using these equations we obtain Wong's equations in a pure Yang--Mills gauge theory with the Coulomb gauge fixing. This result is based on the existing analogy between the reduction procedures carried out in our finite-dimensional dynamical system and in Yang-Mills gauge fields.
