The recursive counterterm procedure developed by Bogoliubov, Parasiuk, and Hepp [1], which was briefly described at the beginning of Chapter 9, yields a finite result for each Feynman diagram, order by order in perturbation theory. It is useful to interprete this procedure as an application of a R-operation to the Feynman diagram. All the finite results on… (More)
