Is the world made of loops?

Abstract

I see no good reason to prefer (any version I know of) the `holonomy interpretation' to the `potential interpretation' of the Aharonov-Bohm effect. Everyone agrees that the inverse image $[A]=[A+d\lambda {]}_{\lambda }=d^{-1}F$ of the electromagnetic field $F$ is a class, full of individuals; and that the circulation $\text{C}$ of the electromagnetic potential $A$ around a loop ${\sigma }_0$ encircling the solenoid is common to the whole class $[A]$, and to the homotopy class or \emph{hoop} $[{\sigma }_0]$. If picking individuals out of classes is the problem, picking an individual potential out of $[A]$ should be no worse than picking an individual loop out of $[{\sigma }_0]$. The individuals of $[A]$ can moreover be transcended---punctually, without integration around loops---by an appropriate version of the electromagnetic connection.

comments welcome
