The technique of extended dualization developed in this paper is a path-integral method for the bosonization of quantized fermion systems in arbitrary dimension D. In its original (minimal) form, dualization is restricted to models wherein it is possible to define a dynamical quantized conserved charge. We generalize the usual dualization prescription to include systems with dynamical non-conserved quantum currents. Bosonization based on this extended dualization requires the introduction of an additional rank 0 (scalar) field together with the usual antisymmetric tensor field of rank (D-2). Our generalized dualization prescription permits one to clearly distinguish the arbitrariness in the bosonization from the arbitrariness in the quantization of the system. We study the bosonization of the most general quantization of the massive Thirring model in arbitrary dimension. Dualization permits one to bosonize this model trivially by invoking the bosonization of the free massive Dirac fermion. We also apply our extended dualization to the bosonization of the Chiral Schwinger model. For this model, minimal dualization is inadequate. We show that two independent scalar fields are required to describe the chiral current in the most general quantization of the Chiral Schwinger model.
