An. Theron et al., BOSONIZATION IN D=2 FROM FINITE CHIRAL DETERMINANTS WITH A GAUSS DECOMPOSITION, Physical review. D. Particles and fields, 56(10), 1997, pp. 6706-6709
We show how to bosonize two-dimensional non-Abelian models using finit
e chiral determinants calculated from a Gauss decomposition. The calcu
lation is quite straightforward and hardly more involved than for the
Abelian case. In particular, the counterterm <A(A)over bar>, which is
normally motivated from gauge invariance and then added by hand, appea
rs naturally in this approach. [S0556-2821(97)01622-6].
