The Number of Feynman Diagrams
Physical Review, 1953The Feynman-Dyson formulation of a perturbation expansion for quantum field theory allows one to give a general combinatorial treatment to the Feynman diagrams involved. A very simple analysis for the total number of such diagrams, $T(n, \ensuremath{\epsilon}, \ensuremath{\rho})$, in quantum electrodynamics, leads to: $T(n, \ensuremath{\epsilon ...
