Abstract

An algorithm for the automatic generation of Goldstone and Bloch-Brandow diagrams, needed for diagrammatic perturbation expansions, is described (the Bloch-Brandow diagrams are required for degenerate perturbations). Diagrams are produced in sets, each set consisting of members related by exchanges about interaction lines. Only distinct connected diagrams are generated. Applications are described.
