A Primer on Functional Methods and the Schwinger-Dyson Equations
Published 25 Aug 2010 in hep-ph | (1008.4337v2)
Abstract: An elementary introduction to functional methods and the Schwinger-Dyson equations is presented. Emphasis is placed on practical topics not normally covered in textbooks, such as a diagrammatic method for generating equations at high order, different forms of Schwinger-Dyson equations, renormalisation, and methods for solving Schwinger-Dyson equations.
