摘要：

We analyze an abelian gauge model in three dimensions which includes massless scalar matter fields. By controlling the trace anomalies with a local dilatation Ward identity, we show that, in perturbation theory and within the BPHZL scheme, the Chern-Simons Simons term has no radiative corrections. This implies, in particular, the vanishing of the corresponding beta-function in the renormalization group equation.
