Transitive set

Also a warm welcome from me. In transitive set, you write that A is transitive if "whenever x∈A, and y∈x, then y∈x." There seems to be some mistake here; perhaps the last "y∈x" should be "y∈A"? Apart from that, it is a nice start, though it could probably be expanded (I don't know enough set theory to do it myself). By the way, you can write [[class (set theory|]] instead of [[class (set theory)|class]]. In addition to the pile of materials suggested by Longhair, you might be interested in Wikipedia:WikiProject Mathematics, which is specifically about mathematics.

Done. Thanks Arthur Rubin 23:59, 16 August 2005 (UTC)[reply]

Point (topology)

I've redirected Point (topology) to Point, which is something anyone can do or undo. There are quite a few pages which link there [1] so it seems possible someone will want to revert this, which wouldn't be an option if it had been speedy deleted. Kappa 13:40, 18 August 2005 (UTC)[reply]

That may be a better choice, although it still should be [[Point (mathematical structures)]], or something like that. The best in the enemy of the good. -- Arthur Rubin 16:34, 18 August 2005 (UTC)[reply]

Regarding the Mathematician Wikipedians category

Hi, it has been suggested that Category:Mathematician Wikipedians be deleted, because it is a duplicate of the more correctly named Category:Wikipedian mathematicians. I would recomend you simply edit your userpage and add yourself to Category:Wikipedian mathematicians (or one of it's sub-categories) instead by adding this to your userpage:

[[Category:Wikipedian mathematicians|{{subst:PAGENAME}}]]

If you disagree your can visit Wikipedia:Categories_for_deletion#Category:Mathematician_Wikipedians and vote against the deletion or just voice your opinion. --Sherool 22:15, 28 August 2005 (UTC)[reply]

Science pearls

Hi,

Please notice the above project. As a mathematician, you might be especially interested in List of publications in mathematics

I’ll appreciate any help. Thank, APH 10:04, 18 September 2005 (UTC)[reply]

Hi Arthur. I've replied on my talk page. Paul August ☎ 14:31, 5 October 2005 (UTC)[reply]

coercive monopoly

Hi. Since you participated in the AfD for coercive monopoly, you might be interested in the major rewrite I just did. I'm sure there will be considerable discussion ensuing (there's an RFC already), and a cool head such as yours would be useful. Rd232 11:58, 10 October 2005 (UTC)[reply]

As a result of the above RfC, I am trying to assist with this article, as well. Your contributions would no doubt be appreciated. -- BBlackmoor ^(talk) 19:02, 13 October 2005 (UTC)[reply]
