Functional Approach to Strong-Coupling in (QED)4 and (QCD)4
In these Lectures, the “Infrared (IR) Method” for extracting relevant low-frequency behavior is described for four-dimensional QED and QCD, using different techniques appropriate to the different theories. The subjects briefly covered are the following.

To the author’s best knowledge, such material first appeared in the monographs Field Theory, by J. Rzewuski, (PWN Publishers, 1972), and Functional Methods and Models in Quantum Field Theory, by H.M.
