Bosonization in d=2 from finite chiral determinants with a Gauss decomposition
Abstract
We show how to bosonize two-dimensional non-abelian models using finite chiral determinants calculated from a Gauss decomposition. The calculation is quite straightforward and hardly more involved than for the abelian case. In particular, the counterterm A A, which is normally motivated from gauge invariance and then added by hand, appears naturally in this approach.
