Weyl's gauge argument
The standard U(1) ''gauge principle'' or ''gauge argument'' produces an exact potential A=df and a vanishing field F=ddf=0. Weyl has his own gauge argument, which is... -

Shortening the gauge argument
The ''gauge argument'' is often used to 'deduce' interactions from a symmetry requirement. A transition---whose justification can take some effort---from global to... -
Is the world made of loops?
In discussions of the Aharonov-Bohm effect, Healey and Lyre have attributed reality to loops $\sigma_0$ (or hoops $[\sigma_0]$), since the electromagnetic potential... -
Logic of gauge
The logic of gauge theory is considered by tracing its development from general relativity to Yang-Mills theory, through Weyl's two gauge theories. A handful of...
