Title: Operator regularization and noncommutative ChernSimons theory
Abstract: We examine noncommutative ChernSimons theory using operator regularization. Both the ζ function and the η function are needed to determine one-loop effects. The contributions to these functions coming from the two-point function is evaluated. The U(N) noncommutative model smoothly reduces to the SU(N) commutative model as the noncommutative parameter θ μν vanishes.PACS Nos.: 11.10.z
