自对偶Yang-Mills理论中的无穷多守恒律

Infinitely many conservation laws in self-dual Yang--Mills theory

C. Adam, J. Sanchez-Guillen, A. Wereszczynski

摘要:

利用规范场的非定域场变换(Cho-Faddeev-Niemi-Shabanov分解)和广义可积性的思想,我们在SU(2)Yang-Mills理论的自对偶扇区中导出了一族新的无穷多守恒流.这些电流可能与保持约化目标空间上的同形性的区域有关。计算是在一个完全协变的方式,因此,可以应用到自对偶方程在任何时空维度与任意签名。

英文摘要:

Using a nonlocal field transformation for the gauge field known as Cho--Faddeev--Niemi--Shabanov decomposition as well as ideas taken from generalized integrability, we derive a new family of infinitely many conserved currents in the self-dual sector of SU(2) Yang-Mills theory. These currents may be related to the area preserving diffeomorphisms on the reduced target space. The calculations are performed in a completely covariant manner and, therefore, can be applied to the self-dual equations in any space-time dimension with arbitrary signature.
