Phys. Rev. D 7, 2943–2949 (1973)Equivalence Theorem on Bogoliubov-Parasiuk-Hepp-Zimmermann-Renormalized Lagrangian Field TheoriesReceived 6 October 1972; revised 15 January 1973; published in the issue dated 15 May 1973 The equivalence theorem for Bogoliubov-Parasiuk-Hepp-Zimmermann-renormalized Lagrangian field theories is proved by means of Feynman graphs. The transformation of Green's functions under a transformation of the Lagrangian vertex is also derived. © 1973 The American Physical Society URL:
