- I have received a few requests for references on the connection between fast
- growing functions and independence results in Peano Arithmetic, which I
- mentioned in a casual comment on one of my previous postings. As it turned
- out, that comment sparked an interest in the topic, and I realized my posting
- was rather incomplete, thus this brief note.
-
- People with some background in logic could try Smorynski's _Lectures on non-
- standard models of Arithmetic_ (Logic Colloquium '82 pp.1-70), after that
- I am told that Ketonen-Solovay's _Rapidly growing Ramsey functions_ (Annals
- of Math. 1981, pp.267-314) is the way to go (it deals with the combinatorial
- issues of the Paris-Harrington incompleteness phenomena).
-
- For further developments in this area (as well as for the connections between
- large cardinals and real numbers, which were recently mentioned in an article
- by W.Boshuck @macgill) you can look up the book _Harvey Friedman's Research
- on the Foundations of Mathematics_ (Harrington et al. North Holland.1986),
- which contains some of the most striking independence results, obtained by
- Prof. Harvey Friedman, here at Ohio State University. It also contains at the
- end very readable accounts from Craig Smorynski, and one entirely accessible to
- non-experts by Gina Kolata (NY Times Math Editor), which is reprinted from
- _Science_ magazine (1980-1983?,anyway all her articles make great reading).
-
- You might also try his lecture at the AMS Centennial entitled _The Incomplete-
- ness Phenomena_ (in _Mathematics into the Twenty-first Century_ F.Browder ed.
- AMS. 1991). By the way, IMO this volume is a *must have*: it contains all the
- plenary addresses given by: Michael Aschbacher, Luis Cafarelli, Persi Diaconis,
- Charles Fefferman, Michael Freedman, Harvey Friedman, Benedict Gross, Roger
- Howe, Vaughan Jones, Victor Kac, Andrew Majda, Karen Uhlenbeck and Edward
- Witten... at just $99 its a bargain!.
