“…From the commutator algebra C (1) , the constraint-set K (2) obeys the commutator algebra A(K (2) ): [φ (4) i , φ (4) j ] = ihΘ ij , [ψ (2) i , φ (4) j ] = ihδ ij , [ψ (2) i , ψ (2) j ] = 0, (4.14) which shows that K (2) is in the second-class. Therefore, the constraint quantum system S * will be constructed through the star-product quantization formalism of POM [2,4,7].…”
