| dc.description.abstract | We show that to n loop order the divergent content of a Feynman amplitude is spanned by a set of
basic (logarithmically divergent) integrals I
(i)
log(λ2), i = 1, 2,...,n, λ being the renormalization group scale,
which need not be evaluated. Only the coefficients of the basic divergent integrals are show to determine
renormalization group functions. Relations between these coefficients of different loop orders are derived. | en_US |
