I disagree with the sentence:
- "it means that such a theory is not an effective field theory because it is well-defined at arbitrarily small distance scales."
If an effective field theory is approximated to low energies, it may well be possible for the remaining theory to have a UV fixed point. When adding higher correction for higher energy, of course, the theory will most probably not be renormalizable any longer, so that speaking of a UV fixed point becomes pointless. IMHO the difference between an effective field theory and a full theory is not it being "well-defined" at arbitrarily small distance scales, but it being "correct". David

Rename
[edit]I suggest this article be renamed to Ultraviolet fixed point ratther than UV fixed point. 70.250.199.40 (talk) 01:24, 25 October 2010 (UTC)
