Talk:Bracket algebra

Nice one for creating the stub. I know very little about these things, how does this relate to algebraic bracket (a redirect to Nijenhuis-Richardson bracket) and related structures. --Salix alba (talk) 14:23, 11 July 2007 (UTC)[reply]

I don't think they do.--Cronholm¹⁴⁴ 23:06, 11 July 2007 (UTC)[reply]

Since this article linked to projective invariants (plural) and that page does not exist, I decided to created a redirect page with that title, linking to projective invariant. I was surprised that that does not exist either. Can someone here create it? (If, as I surmise, it simply means a quantity that, like the cross-ratio, is invariant under projectivities, then I could create a stub. But maybe someone else can do better than a mere stub.)
