| Abstract: | Based on the configuration-space generating functional obtained by using the Faddeev-Popov trick for a gauge-invariant system,
the Ward identities for global transformation are derived. The conservation laws at the quantum level for global symmetry
transformation are also deduced. A preliminary application of the present formulation to non-Abelian Chern-Simons (CS) theory
is given. The Ward identity and quantal BRS charge under the BRS transformation are deduced. The quantal conserved angular
momentum is obtained and the fractional spin for CS theories is discussed. |
