Thanks! I only joined CZ because I thought the world needed a decent introductory account of set theory :-) Mark Wainwright 04:22, 9 May 2010 (UTC)
Are you sure the world needs nothing else? :-) Boris Tsirelson 07:57, 9 May 2010 (UTC)

Probably this article is approvable. For now I am not ready to approve it, because some finer points are beyond my competence. I understand the given text about that, but I have no other sources to be sure. Namely:

  • "An ingenious axiom of Goedel's, Limitation of Size";
  • "Montague proved in 1961 that ZF cannot be finitely axiomatised";
  • "NF ... is finitely axiomatisable";
  • "NFU, whose consistency is implied by that of simple type theory".
