Hi, I though you might be interested in the discussion at Wikipedia talk:WikiProject Mathematics#Computability, recursion theory. Cheers, —R. Koot 00:01, 1 December 2005 (UTC)

[edit] Wikireason

Hi, I saw a comment you wrote on the Mediawiki mailing list, and it seemed like you may have started a project similar to my own: Wikireason. It's a wiki dedicated to analyzing arguments in a logical manner. Hope to see you around. AdamRetchless 22:37, 28 June 2006 (UTC)

[edit] Attractor

A few points:

  • The set B(A) is too large, as it requires that all neighborhoods go to the attractor, when what is normally defined is that nearby points go to the attractor.
  • A system in one dimension can have a space-dependent velocity field, so the example f(t, (x,v)) = x + t v doesn't quite work.
  • The invariance follows from the two conditions, (1) f(t, Λ) ⊃ Λ for large t together with (2) the existence of a fundamental neighborhood that ends up in any open containing the attractor. The invariance condition is redundant.

The definition I had written (equivalent to the one you have given) for an attractor was the definition given by Ruelle for an attracting set (not attractor). An attractor in Ruelle's definition needs to have some stability against small perturbations, which the current definition does not address. – XaosBits 20:48, 21 September 2006 (UTC)

[edit] United States National Guard

I noticed you put a disputed tag on the United States National Guard page, but where is your reason? Your edit summary says "bit about intent of founding fathers and stuff" what is the disute? Could you either go to the Talk:United States National Guard page and state your case or remove the tag? When I saw the tag I was ready to throw my pro or con into the fray, but I was disappointed to see there was no fray. --Colputt 16:31, 19 July 2007 (UTC)

[edit] New article on Kleene's O

Since you added material on Kleene's O to the article ordinal notation which I reverted, I wanted to let you know that I used it as the basis for creating a new article on Kleene's O itself. You might want to add your ideas to that article. Ordinal notation is a narrower concept where each system of ordinal notations is recursive as a whole. Kleene's O as a whole is \Pi^1_1 rather than recursive. JRSpriggs (talk) 02:14, 6 March 2008 (UTC)

[edit] Usernames

I would like you to consider changing your username. Please understand that, although you mean no particular harm by it, you are cheapening the term - and making light of the organized butchery of millions of people. You may post a request at Wikipedia:Changing username.

Thank you in advance. DS (talk) 01:05, 4 April 2008 (UTC)
