Abstract
Using the exact path integral solution of the Schwinger model — a model where instantons are present — the Dyson-Schwinger equations are shown to hold by explicit computation. It turns out that the Dyson-Schwinger equations separately hold for every instanton sector. This is due to theΘ invariance of the Schwinger model.
