Abstract
We discuss the equivalence of two dual scalar field theories in two di mensions. The models are derived though the elimination of different f ields in the same Freedman-Townsend model. It is shown that tree S mat rices of these models do not coincide. The two-loop counterterms are c alculated. It turns out that while one of these models is single-charg ed, the other theory is multicharged. Thus the dual models considered are nonequivalent on classical and quantum levels. This indicates the possibility of the anomaly leading to nonequivalence of dual models.
