[edit] Question
Isn't it the complete graph of order 5 instead of 6?

- The Ramsey number R(3,3)=6, which I assume that you are referring to, is the first number where a blue triangle or a red triangle is forced. The largest monochromatic triangle free edge coloring is on the complete graph with 5 vertices, so 6 vertices forces a monochromatic triangle. Ramsey numbers are always one larger than the largest coloring of the given type. (My personal POV is that this is an irritant, since I often misstate Ramsey numbers by one as a result. I'd change it if I could, but they were defined before I was born. ;o) ) --Ramsey2006 07:14, 15 December 2006 (UTC)
[edit] Macroeconomics
Recently, an editor added the following paragraph at the top of the page:
Frank Ramsey posed the question of how much a nation should save solved it by using a model that is now the prototype for studyng the optimal intertemporal allocation of resources.
Since this has nothing at all to do with Ramsey theory, I moved it here. -- Dominus 15:06, 25 March 2007 (UTC)
