A translation of the paper: On the question of avoiding the infinite "self-reaction" of the electron, by V. Ambarzumian and D. Ivanenko (1930)

Abstract

An attempt is made to avoid the difficulty of the infinite reaction of the electron on itself, which occurs in quantum electrodynamics, by introducing difference equations instead of differential equations. This vision allows the difficulty of the relativistic wave equation emphasised by Klein, for example, to be essentially eliminated.
