Definition talk:Closure (Abstract Algebra)
Absolutely. I will try to do it sometime this week when I have five minutes, unless someone else provides the details first. lasserempe 22:45, 16 February 2009 (UTC)
Two different contexts for "closure"
I have tried to separate the definition for "closure" in the context of abstract algebra from the more specific definition in the context of topology.
If you find any instances of the latter context pointing towards the "abstract algebra" definition, please change the link to Definition:Closure (Topology). Thx. --prime mover (talk) 21:17, 21 February 2009 (UTC)
With the upcoming advent of some generalities, I would like 'closure' to be defined for arbitrary operations (like there are: union, intersection (i.e., over arbitrary index sets), and various more) but I haven't got the background to write such a page with enough rigour myself (I think). Anyone willing to help me? --Lord_Farin 02:47, 30 May 2012 (EDT)
