Talk:Additively closed

I'd just like to say that my editing this article is in no way meant to support its continued existence. I'm considering an AFD, or moving it to closed under addition, and I won't protest either move by anyone else.

While multiplicatively closed subsets of rings, groups, and monoids are often considered, additively closed subsets are pretty much used only in conjunction with a positive convex cone to define an order on a vector space ... and the article on convex cones seems to handle them just fine. The examples seem obvious.

 * I would endorse this view - the whole article seems fairly trivial, and I think it is hard to visualise it ever becoming a useful fully-fledged article. Madmath789 23:18, 2 June 2006 (UTC)
