Probing the Consistency of Quantum Field Theory I - From Nonconvergence to Haag's Theorem (1949–1954)

This Element covers the years immediately following the development of renormalized quantum electrodynamics. It begins with the realization that perturbation theory cannot serve as the foundation for a proof of consistency, due to the non-convergence of the perturbation series.
