[edit] Closeure (topology)

A separate article is titled closure (topology). Should these two articles be merged? -- Michael Hardy, 2003 Aug 12

IMO, no; see my reply on Talk:Closure (topology). -- Toby Bartels 05:13, 25 Sep 2003 (UTC)

[edit] Closed "over addition/subtraction etc"

Should this be the page to include what it means to be "closed over addition" or the like? (meaning that if x and y are part of the set, x+y must also be part of the set). Fresheneesz 20:21, 17 March 2006 (UTC)

I would say no, as that type of closure is covered by Closure (mathematics). Closure under an operation is not related to whether a set itself is closed in some space. - grubber 21:33, 17 March 2006 (UTC)

Though we can certainly link that in the disambig info at the top. -lethe ^{talk +} 06:03, 18 March 2006 (UTC)

I think that's a great idea. - grubber 17:59, 19 March 2006 (UTC)
