Gauge conditions for an Abelian Chern-Simons system consistent with equations of motion

Complete constraint analysis and choice of gauge conditions consistent with equations of motion is done for Abelian Chern-Simons field interacting min imally with a complex scalar field. The Dirac-Schwinger consistency conditi on is satisfied by the reduced phase space Hamiltonian density with respect to the Dirac bracket. It is shown that relativistic invariance under boost s can be obtained only if gauge conditions were chosen consistent with the equations of motion. Moreover all gauge-invariant quantities are shown to b e free of transformation anomaly.
