In fact, the latter is the maximal subalgebra; the set {, } is the minimal subalgebra. Given any Boolean algebra (A, ≤) and an arbitrary subset X of A, we have the subalgebra of (A, ≤) generated by X. This may be defined as the least (smallest) subalgebra of (A, ≤) containing X.

Web25 Feb 2024 · If there is a finite system $ S $ with the above properties, then $ A $ is called a finitely-generated algebra. The smallest numbers of elements in a system of generators is called the number of generators of the algebra. WebLet R be a finitely generated Z -algebra, and m ⊂ R a maximal ideal. We wish to show R / m is a finite field. Let i: Z → R be the unique ring map; then i − 1(m) is a maximal ideal in Z (as R is finitely generated over Z), and thus Z / i − 1(m) is a finite field Fp for some prime p.
