Resurgent Analysis of Ward-Schwinger-Dyson Equations
Marc P. Bellon, Enrico I. Russo
Building on our recent derivation of the Ward-Schwinger-Dyson equations for the cubic interaction model, we present here the first steps of their resurgent analysis. In our derivat…

Ward-Schwinger-Dyson equations in Quantum Field Theory
Marc P. Bellon, Enrico I. Russo
We develop a system of equations for the propagators and three point functions of the quantum field theory in six dimensions. Inspired from a refinement by Ward on the Schwin…
