if we know that the divergent series in perturbation theory of quantum field theory goes in the form:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]\sum_{n=0}^{\infty}a(n)g^{n}\epsilon^{-n}[/tex] with

[tex]\epsilon\rightarrow{0} [/tex]

then ..how would we apply the renormalization procedure to eliminate the divergences and obtain finite results?....why can not this be done to NOn-renormalizable series?..thanks.
