Webtype in Example (vi). LEMMA 3. In a commutative Artinian ring every prime ideal is maximal. Also, there are only nitely many prime ideals. PROOF. Consider a prime P ˆA. Consider x 62P. The power ideals (xm) decrease, so we get (x n) = (x +1) for some n. Then x = axn+1, so xn(1 ax) = 0. But xn 62P, hence 1 ax 2P, which implies A = P+Ax. Thus P ...
