The problem is then reduced to an Abelian version of two-dimensional bosonization with extra ``internal'' coordinates. On a formal level, putting these internal coordinates on a finite lattice seems to provide a well-defined prescription for calculating correlation functions. However, in the infinite-lattice or continuum limits, certain difficulties appear that require very delicate specification of all of the many limiting procedures involved in the construction.Based on a talk given by C.
