The renormalizable QFT is the theory with only a finite number of Feynman diagrams superficially diverge(in all order) and the non-renormalizable QFT is the theory with infinite diagrams superficial diverge.(adsbygoogle = window.adsbygoogle || []).push({});

Then my question is in all renormalizable theories can we absorb all divergences into counter terms or not?(All renormalizable theories are ''really renormalizable'')

Is there any case in non-renormalizable QFT we can absorb all divergences into counter terms?
