| Abstract: | In the framework of Faddeev-Senjanovic (FS) path-integral quantization, CP
1 nonlinear σ model coupled to Non-Abelian Chern-Simons (CS) fields is quantized. Generalized canonical Ward identities (WI) are deduced
from the invariance of the canonical effective action under gauge transformations, which are obtained from the generators
of gauge transformations, including all first-class constraints, in Dirac’s sense. The generalized canonical WI has brief
form and is equivalent to canonical WI under gauge transformations in Dirac’s sense.
