If I'm not mistaken, it was in his seminal paper “An Essentially Undecidable Axiom System”, published in

Proceedings of the International Congress of Mathematics (1950), 729–730,

where R.M. Robinson proved that Gödel Incompleteness Theorem still applies to Peano Axioms if we drop the induction schema (hence showing that infinite axiomatization is not necessary for essential undecidability), in what we now call Robinson Arithmetic.

I would like to know:

  • Is actually this paper what I should be looking for?
  • Can it be found anywhere on the net? (I already tried on MathSciNet, SpringerLink, JSTOR and Google Scholar, without success)
  • Can anyone pinpoint to closely related, or at least similar, accessible papers?

(Note: I already have the book "Undecidable theories", which he published in collaboration with Tarski, but I'd prefer to locate papers about 'Robinson theory', specifically).

    $\begingroup$ One can easily find the cited work via the links given by John Stillwell and Felipe Voloch. However, it is only a one-page abstract. It seems that contributed papers were not actually printed in the Proceedings? $\endgroup$ – Nate Eldredge Sep 15 '10 at 21:37

Hi Jose, it's in the British library collection: http://snurl.com/z16ud Haven't checked what the fees are, but you could order it from there.

Alternatively, you could try the LMS: http://www.lms.ac.uk A good chance they will have the procs in their library, and you can get photocopies for a nominal fee.

Several other similar alternatives too.

  • $\begingroup$ Thanks Bob! But I'd like to find it 'online' (i.e., in electronic format), if possible (if not, I will resort to your nice suggestions!) $\endgroup$ – Jose Brox Jul 5 '10 at 23:31
  • $\begingroup$ Oh, on a closer inspection I see that the British Library offers the option of sending an electronic copy, but the fee is indeed a bit high (over 8 pounds). I'd like to get free access to the article from my University, if possible. $\endgroup$ – Jose Brox Jul 5 '10 at 23:36

    $\begingroup$ I know this is not a discussion blog , I make it short : How disgraceful it is to have to pay for work that was done with our taxes!! $\endgroup$ – Jérôme JEAN-CHARLES Oct 3 '10 at 1:30
