Under homotopically non-trivial gauge transformations, ci,,, with winding number n, the action, I, for topologically massive Yang-Mills theory changes by 2nn: I-+ I + 2nn. Equivalently, Gauss' law requires the physical states vl,,,[A] to change by a phase under time-independent gauge transformations
