WebIt was shown using the Schwinger-Dyson equations and the Slavnov-Taylor identities of Yang-Mills theory that no inconsistency arises if the gluon propagator behaves like (1/p/sup 2/)/sup 2/ for small p/sup 2/. To see whether the theory actually contains such singular long range behavior, a nonperturbative closed set of equations was formulated by neglecting … In perturbative quantum field theory the Schwinger-Dyson equation (Dyson 49, Schwinger 51) equates, on-shell, the time-ordered product of the functional derivative of the action functional SS for a free field theory and another observable AA with the time ordering of the corresponding functional … See more For details and proof see at BV-operator this prop., following Rejzner 16, remark 7.7, following Henneaux-Teitelboim 92, section 15.5.3 See more The equation is originally due to 1.
