Submitted paper: Haag’s Theorem as a Reason to Reconsider Direct-Action Theories
ABSTRACT. It is argued that the severe consequences of Haag’s inconsistency theorem for quantum field theories can be successfully evaded in the direct-action approach. Some recent favorable comments of John Wheeler, often mistakenly presumed to have abandoned his own (and Feynman’s) direct-action theory, together with the remarkable immunity of direct-action quantum electrodynamics to Haag’s theorem, suggest that it may well… Read more →
