WebMar 3, 1994 · We review the current status of nonperturbative studies of gauge field theory using the Dyson-Schwinger equation formalism and its application to hadronic physics. We begin with an introduction to the formalism and a discussion of renormalisation in this approach. We then review the current status of studies of Abelian gauge theories [e.g., … WebApr 10, 2015 · We compute the pion quark Generalized Parton Distribution H {sup q} and Double Distributions F {sup q} and G {sup q} in a coupled Bethe-Salpeter and Dyson-Schwinger approach. We use simple algebraic expressions inspired by the numerical resolution of Dyson-Schwinger and Bethe-Salpeter equations.

WebStarting from the superstring amplitude describing interactions among D-branes with a constant world-volume field strength, we present a detailed analysis of how the open string degeneration limits reproduce the corresponding field theory Feynman diagrams. Webon Dyson{Schwinger equations, which was already suggested in the work of Bergbauger{Kreimer [2]. In x4 we show that Dyson{Schwinger equations can be formulated in the operad setting, using a family of grafting operations, which is not required to satisfy a cocycle condition. We consider Dyson{Schwinger equations on an operad of ow charts.
