A question I would like to get an answer is when is a QFT exactly solved? E.g. if I know the solution of the equation for the two-point function I have got all about the theory? This equation is classical in nature being the two-point function defined in the sense of distributions. I have read the original paper of Schwinger about QED2 and he does exactly this.(adsbygoogle = window.adsbygoogle || []).push({});
