``Re: algebra or ring'' by HkBst on 2004-10-17 09:26:11
But logically it should be defined for something which I will call here a nonassociative ring. The extra operation of scalar multiplication that an algebra has over a ring is superfluous.

Hmmm, it also seems there is no definition of a generalized ring on PM. Maybe I will make an entry sorting this stuff out.
