User talk:Ramsey2006

From Wikipedia, the free encyclopedia

Welcome, Ramsey2006!

It was a joy to read your contribution to the Ramsey theory article, and especially to view your nice illustration. You seem fairly advanced for a beginner; am I right in surmising that you've had some prior wikipedia and mathematics experience?

I've got an idea of contributing a little myself to the article, when I get around to it. I think that as this is supposed to be an encyclopædian article, there should be some mentioning of the context of the original theorems (Theorems A and B in his "On a problem of formal logic"), and also a mentioning of the fact that the infinite and hypergraph variants are in fact original, not later extensions. Do you have any comments? JoergenB 23:35, 13 October 2006 (UTC)

Well, if you never did any wiki work before, your start was an even better achievement. You must have the habit of reading and understanding instructions - so, again, that indicates a practiced mathematician :-)

I discovered wikipedia just a couple of months ago, which is another reason I didn't put a 'Welcome' template on your talk page; but since you are new, perhaps I should look it up. It does contain some links and advices; but perhaps you've already found it elsewhere.

I've access to a good mathematical library (at the University of Stockholm), which I found sometimes is a great advantage on the wiki, too. Ramsey's article is in Proc. London Math. Soc. 30 (1930), pp. 264-286. (Actually, I never read it before, either.) Of course he doesn't use the term hypergraph; he talks about colouring all those sub-classes of [the given class] which have exactly r members.

So, you have the full right to remain anonymous and do not need to answer; but if I understand your comment about your own work correctly, I'd guess your surname starts with F, K, or R... JoergenB 12:58, 14 October 2006 (UTC)

Thank you for the reference!

I'll send a letter outside the wiki system for OR related stuff. One of the things I decided I have to learn about is Graham numbers; the thing is contradictory as it stands; and there is some confusion about what Graham (and Rotschild) really did or didn't do. I wrote a little 'correction' which unhappily was not quite correct, either, so I've started tryinng to assimilate the Graham-Rotschild theorem. I've already found out that the article covers both the (Euclidean space) cube example and the (GF(2) space) secretary one, although they are different and may lead to different estimates. Moreover, even if the interest among wikipedians and readers center among the enormous numbers, I think that the Graham-Rotschild theorem itself should be stressed more, and in particular the fact that both Ramsey's (finite) theorem and van der Waerden's theorem are special cases.

[edit] Talk pages

There are some good tips at Wikipedia:Talk pages. Splitting comments makes it hard to follow who is saying what. -Will Beback · † · 04:15, 20 November 2006 (UTC)
