DoFun

DoFun is a Mathematica package for deriving various types of functional equations:

  • Derivation of Dyson-Schwinger equations
  • Derivation of functional renormalization group equations
  • Derivation of equations for correlation functions of composite operators
  • General framework for handling functional expressions
  • Simplistic automated plotting of Feynman diagrams
  • Conversion of symbolic expressions into algebraic ones

The code can be found in a GitHub repository.
