Global Gauge Symmetries and Spatial Asymptotic Boundary Conditions in Yang-Mills Theory

Silvester G. A. Borsboom, Hessel B. Posthuma

In Yang-Mills theory on a Euclidean Cauchy surface, the physical gauge group is often taken to be ${\mathcal{G}}^I/{\mathcal{G}}_0^{\infty }$, where ${\mathcal{G}}^I$ consists of boundary-p…
