[edit] The fundamental theorem of additive polynomials

Let P(x) be a polynomial with coefficients in k, and \{w_1,...,w_m\}\subset k be the set of its roots. Assuming that P(x) is separable, then P(x) is additive if and only if {w1,...,wm} form a group.

They are a subgroup in respect to addition or multiplication?

Should it be

\{w_1,...,w_m\}\subset \bar{k}

instead of

\{w_1,...,w_m\}\subset k?


[edit] Mathworld

Hmm, the structure of this article shows remarkable similarity to the Mathworld article. linas 05:03, 10 Jun 2005 (UTC)

I noticed that a while ago too.
By the way, could you check my edits for correctness? Back then both of us were green and we fought like hell. :) Oleg Alexandrov 05:14, 10 Jun 2005 (UTC)
