A. Foussats et al., NONLINEAR SIGMA-MODEL IN THE FADDEEV-JACKIW QUANTIZATION FORMALISM, International journal of theoretical physics, 36(12), 1997, pp. 2923-2935
The key equations of the symplectic Faddeev-Jackiw formalism are writt
en in an alternative way so that the inverse of the symplectic matrix
is easily found. The nonlinear sigma model including the Hopf term in
the action is treated in the framework of this quantization method. It
is shown how the complete dynamics of the system is described by mean
s of the generalized Faddeev-Jackiw quantum brackets.
