A pedagogical introduction to nonequilibrium theory, time-dependent phenomena and excited state properties, for graduate students and researchers.We now show that this fact is generally true: every vacuum diagram with N3 symmetry operations splits into classes of NS ... Therefore, superimposing the two selfenergies we find a one-to-one mapping between the vertex labels thatanbsp;...
