This quantity corresponds to a one-form in an effect which is due to the monodromy of the path taken by a particle.
This quantity corresponds to a one-form in an effect which is due to the monodromy of the path taken by a particle. The Proca Lagrangian has a term with a mass times the square of this quantity. A field tensor usually denoted "F mu nu" is equal to "d mu times this quantity sub nu" minus "d nu times this quantity sub mu". That covariant form of this quantity must be added to the QED Lagrangian to preserve gauge invariance. This quantity at x equals mu over four pi times the integral over all space of the current density over x minus x prime d x prime. This quantity's gauge transformation involves adding the gradient of a function. Its divergence is zeroin the Coulomb gauge. The electric field has a term equal to minus this quantity's time derivative and a term equal to minus the gradient of a similar scalar quantity. For 10 points, name this quantity whose curl gives the magnetic field, which is symbolized A.
