Topologically distinct Feynman diagrams for mass operator in electron-phonon interaction
The new method for designing topologically distinct Feynman diagrams for electron's mass operator in electronphonon interaction is developed using the permutation group theory. The carried out classification of DPs allows to choose the classes, corresponding to disconnected diagrams, to singl...
