P and T transformations of EM vector potential

  1. Apr 9, 2009 #1
    Help! What are the P and T transformation laws for the electromagnetic vector potential, [itex]A_\mu[/itex]? and how are these consistent with the transformation laws of the electric and magnetic vectors that I am familiar with?

    under P: E is odd, B is even
    under T: E is even, B is odd

    When I try to use the formulas,
    [tex]\mathbf{E}=-\nabla\phi-\frac{\partial\mathbf{A}}{\partial t}[/tex]
    I get incorrect results.
