Abstract
The (2 + 1)-dimensional gauged O(3) nonlinear sigma model with
Chern-Simons term is canonically quantized. Furthermore, we study a
nonminimal coupling in this model implemented by means of a Pauli-type
term. It is shown that the set of constraints of the model is modified
by the introduction of the Pauli coupling. Moreover, we found that the
quantum commutator relations in the nominimal case is independent of the
Chern-Simons coefficient, in contrast to the minimal one.
