The Mathworld URL doesn't work for me (right now).

Is importing this from Mathworld (a) OK and (b) worth it?

[edit] Merge with Rig (algebra)

Every reference on semirings that I can find (besides the always dubious MathWorld) defines them to include 0 and 1. Which means this is the same concept as that defined at rig (algebra). Moreover, I can find numerous references on semirings but almost none on rigs. Is this a term that is really used? In any case it seems that "semiring" is more common and "rig" should be redirected here and not the other way around. Comments, objections? -- Fropuff 23:54, 2004 Jul 23 (UTC)

Isn't rig used by John Baez? And isn't that the only obvious reason it made it into WP?

Ahh... there's a theory. I think you may be right. Baez appears to use rig frequently. See "This Week's Finds in Mathematical Physics" 121, 185, 191. His own comment on the matter: [1]. In any case I think I will merge the articles. -- Fropuff 03:47, 2004 Jul 24 (UTC)
