Ideal (ring theory) - Wikipedia
WEBIn mathematics, and more specifically in ring theory, an ideal of a ring is a special subset of its elements. Ideals generalize certain subsets of the integers, such as the even numbers or the multiples of 3.

WEBDe nition-Lemma 15.5. Let R be a ring. We say that R is boolean if for every a 2R, a2 = a. Every boolean ring is commutative. Proof. We compute (a+ b)2. a+ b = (a+ b)2 = a2 + ba+ ab+ b2 = a+ ba+ ab+ b: Cancelling we get ab = ba. If we take b = 1, then a = a, so that (ba) = ( b)a = ba. Thus ab = ba. De nition 15.6. Let R be a ring. We say that R ...
Are ideals also rings? - Mathematics Stack Exchange
WEBApr 20, 2015 · In general, an ideal is a ring without unity - i.e. without a multiplicative identity - even if the ring it is an ideal of has unity. For example $\mathbb{2Z} \subset \mathbb{Z}$ is an ideal but $\mathbb{2Z}$ is not a ring with unity.
Stanley–Reisner ring - Wikipedia
WEBStanley–Reisner ring. In mathematics, a Stanley–Reisner ring, or face ring, is a quotient of a polynomial algebra over a field by a square-free monomial ideal. Such ideals are described more geometrically in terms of finite simplicial complexes. The Stanley–Reisner ring construction is a basic tool within algebraic combinatorics and ...
