Aspects of boundary conditions for non-Abelian gauge theories

The boundary values of the time component of the gauge potential form externally specifiable data characterizing a gauge theory. We point out some of their consequences such as reduced symmetries, bulk currents for manifolds with disjoint boundaries and some nuances of how the charge algebra is real...

Zusammenfassung:The boundary values of the time component of the gauge potential form externally specifiable data characterizing a gauge theory. We point out some of their consequences such as reduced symmetries, bulk currents for manifolds with disjoint boundaries and some nuances of how the charge algebra is realized.
