Summary
The low-energy limit of renormalized Feynman amplitudes is studied inMinkowski space with subtractions performed at the origin. The existence, in the distributional sense, of the low-energy limit of the amplitudes when all the external momenta of the graphs are scaled to zero is established. In particular the limiting forms of the amplitudes at low energies are explicitly derived.
