It is shown that this treatment is equivalent to the Faddeev-Jackiw (FJ) approach. It is also shown that the field redefinitions that transform the fields of the model into BRST and $σ$ closed are actually the Darboux's transformations used in the FJ formalism.10 pages, LaTex, no figuresHigh Energy Physics - Theorytext
