  We consider the minimal chiral Schwinger model, by embedding the gauge
noninvariant formulation into a gauge theory following the
Batalin-Fradkin-Fradkina-Tyutin point of view. Within the BFFT procedure, the
second class constraints are converted into strongly involutive first-class
ones, leading to an extended gauge invariant formulation. We also show that,
like the standard chiral model, in the minimal chiral model the Wess-Zumino
action can be obtained by performing a q-number gauge transformation into the
effective gauge noninvariant action.
