Convolutions of particle Green's functions

Mostrar todas las versiones(2)

The use of Feynman causal function in the perturbative treatment of the S-matrix made the computation of convolutions an easy and well-known procedure for free-particle propagators. But the convolution of its components, like the δ and principal values among themselves, is very rarely looked upon. I...
