We analyze the Hilbert space structure of the isomorphic gauge noninvariant and gauge-
invariant bosonized formulations of chiral QCD 2 for the particular case of the Jackiw …

A two-dimensional Abelian model with quartic interaction among two species of Fermi fields
is analyzed through a functional integral formulation. We consider the bosonization of the …

We consider the minimal chiral Schwinger model, by embedding the gauge non-invariant
formulation into a gauge theory following the Batalin–Fradkin–Fradkina–Tyutin point of view …

We reexamine the two-dimensional model of massive fermions interacting with a massless
pseudoscalar field via axial-current derivative coupling. The hidden Thirring interaction in …

Using a synthesis of the functional integral and operator approaches we discuss the fermion-
boson mapping and the role played by the Bose field algebra in the Hilbert space of two …

We use the Abelian reduction of the Wess–Zumino–Witten theory to perform the functional
integral bosonization of the two-dimensional fermion model with Thirring interaction among …

We present a class of mappings between the fields of the Cremmer–Sherk and pure BF
models in 4D. These mappings are established by two distinct procedures. First, a mapping …

In this work, we show how nonlinear point-coupling models, described by a Lagrangian
density containing only terms up to fourth order in the fermion condensate (̄ψψ), are …

Two different families of abelian chiral gauge theories on the torus are investigated: the aim
is to test the consistency of two-dimensional anomalous gauge theories in the presence of …

We present a class of mappings between models with topological mass mechanism and
purely topological models in arbitrary dimensions. These mappings are established by …
