Naming convention

Why is the title of this article plural? Michael Hardy (talk) 00:34, 12 July 2008 (UTC)[reply]

It looks like the singular "commutation theorem" is also used to identify specific instances. I think this likely to be similar to "isomorphism theorem" versus "isomorphism theorems". The latter sounds more natural due to there being a few of them. Isomorphism theorem begins, "In mathematics, the isomorphism theorems are three theorems," so I think it should be fine for the article name to be different than the introduction.

It is no longer plural. In fact R.e.b. had created a redirect page "Commutation theorem" in 2006. An administrator made the switch over and the redirect was changed to here. Mathsci (talk) 05:01, 12 July 2008 (UTC)[reply]

trace

The link to trace (mathematics) in the lead paragraph is a bit misleading, as there is not very much related material there. Katzmik (talk) 17:26, 29 December 2008 (UTC)[reply]

Yes, that article is sadly incomplete. Traces and norms can be defined on central simple algebras, as in Weil's Basic Number Theory. Mathsci (talk) 18:44, 29 December 2008 (UTC)[reply]
