Example of maximal ideal
WebAnswer (1 of 3): In short, no, not every ring has a maximal ideal. For instance, if a ring R is non-unital then you can make sense of the Jacobson radical J(R) by introducing generalized quasiregular elements and also amend the notion of a simple R-module. One then finds that there exist non-unit... WebMaximal ideal: A proper ideal I is called a maximal ideal if there exists no other proper ideal J with I a proper subset of J. The factor ring of a maximal ideal is a simple ring in general and is a field for commutative rings. ... Examples of ideal operations

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 ... In mathematics, more specifically in ring theory, a maximal ideal is an ideal that is maximal (with respect to set inclusion) amongst all proper ideals. In other words, I is a maximal ideal of a ring R if there are no other ideals contained between I and R. Maximal ideals are important because the quotients of rings by … See more There are other equivalent ways of expressing the definition of maximal one-sided and maximal two-sided ideals.
