Resumen:
We
carry out an analysis of the quantization of anomalous gauge theories
inside the BatalinVilkovisky scheme. Working on the chiral QCD2,
we show that by considering the group elements as dynamical variables
one is able to construct a local solution, the WessZumino term, for
the master equation. Thus the gauge independence of the generating
functional is restored. Also, the BRST charge is built up showing that
in the extended space this operator recovers the nilpotency.
