โฆ Synopsis
The ordinary Schwinger model is studied for a one-parameter class of regularizations commonly used in the study of the anomalous chiral Schwinger model and shown to be sensible and in fact solvable for a range of values of the parameter. There is a massless fermion in the spectrum except at the value which corresponds to the usual treatment of the model.

After having justified the gauge invariant version of the chiral Schwinger model we perform canonical quantization via Dirac brackets. The constraints are First class, exhibiting gauge invariance. As a result we find that this is the reason for the consistency of the model of Jackiw and Rajaraman.
The known operator solution of the massless Schwinger model is used to calculate exactly, in three operator product expansions, the coefficient functions of the first few operators of low dimension which contribute when vacuum matrix elements are to be taken. A comparison of the results provides a t
