Operator product expansion in two-dimensional quantum electrodynamics

An operator product expansion in two-dimensional massless quantum electrodynamics is obtained. A basis of the expansion is obtained in which all the nonanalytic dependences on the coupling constant are contained in the operators. In this basis, there is a correspondence in the leading logarithmic expansion between the exact operator expansion and the standard Wilson expansion. Complete agreement of these expansions requires establishment of the exact connection between the ultraviolet subtraction point for the operators and the infrared subtraction point for the coefficient functions.
