Beschreibung

High Quality Content by WIKIPEDIA articles! The Schwinger-Dyson equation, named after Julian Schwinger and Freeman Dyson, is an equation of quantum field theory (QFT). To make the connection to diagramatical techniques (like Feynman diagrams) clearer, it's often convenient to split the action S as S[f]=1/2 D-1ij fi fj+Sint[f] where the first term is the quadratic part and D-1 is an invertible symmetric (antisymmetric for fermions) covariant tensor of rank two in the deWitt notation whose inverse, D is called the bare propagator and Sint is the 'interaction action'.
