- Descrição
- The use of Feynman causal function in the perturbative treatment of 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 <math>\delta\,\!</math> and Principal values among themselves is very rarely looked upon. In field theories with higher order equations of motion some of these convolutions appear as the fundamental ingredients A discussion of these convolutions is explicitly done in the simplest examples.
