Infinity as an Artifact of the Point Assumption: A Finite-Cutoff Reading of QED Renormalization

Abstract. Quantum electrodynamics is at once the most precisely verified theory in physics and the first site ofits collision with infinity. The Wilsonian resolution reads the divergences as artifacts of extrapolating a fieldtheory to zero distance, but leaves the physical identi...
