The supplementary condition in quantum electrodynamics

  • D. J. Candlin


The difficulties of the supplementary condition are completely analogous to those of the momentum of the centre of mass in non-relativistic bound-state problems. It is unnecessary to introduce an indefinite metric or limiting procedures.


Nei problemi non relativistici degli stati legati le difficoltà della condizione supplementare sono del tutto analoghe a quelle dell’impulso del centro di massa. Non è necessario introduire una metrica indefinita o procedimenti di limite.
