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.

The proper time path-integral representation for the two-body Green's function is derived for several examples of field theory, e.g., the \(\varphi^{3}\) theory in \(4 d\), scalar and spinor QED, and its properties are studied in the quenched approximation. The perturbative expansion is shown to coi
