Algorithmic derivation of functional renormalization group equations and Dyson-Schwinger equations (1102.5307v2)
Published 25 Feb 2011 in hep-th, cond-mat.other, and hep-ph
Abstract: We present the Mathematica application DoFun which allows to derive Dyson-Schwinger equations and renormalization group flow equations for n-point functions in a simple manner. DoFun offers several tools which considerably simplify the derivation of these equations from a given physical action. We discuss the application of DoFun by means of two different types of quantum field theories, namely a bosonic O(N) theory and the Gross-Neveu model.
