Minkowski空间上通过陪集的SO(1,3)Yang-Mills解

SO(1,3) Yang-Mills solutions on Minkowski space via cosets

Kaushlendra Kumar

摘要:

本文在Minkowski空间上提出了一个新的具有规范群SO(1,3)的Yang-Mills解族,它在几何上分为光锥内部和光锥外部两类.我们用SO(1,3)/SO(3)陪集和SO(1,3)/SO(1,2)陪集分别划分前者和后者,并解析求解SO(1,3)不变规范场的Yang-Mills方程。由此产生的领域和它们的应力-能量张量,当翻译到闵可夫斯基空间,发散的光锥,但我们演示了如何这个应力-能量张量可以正则化,由于其独特的代数结构。

英文摘要:

We present a novel family of Yang-Mills solutions, with gauge group SO(1,3), on Minkowski space that are geometrically distinguished into two classes, viz. interior and exterior of the lightcone. We achieve this by foliating the former with SO(1,3)/SO(3) cosets and the latter with SO(1,3)/SO(1,2) cosets and analytically solving the Yang-Mills equation of an SO(1,3)-invariant gauge field. The resulting fields and their stress-energy tensor, when translated to the Minkowski space, diverge at the lightcone, but we demonstrate how this stress-energy tensor could be regularised due to its unique algebraic structure.
