WebOne can go further and replace commutative ring R by a commutative semiring. A semiring has multiplication and addition but no subtraction, in general. It turns out that replacing C by a commutative semiring (for example, Boolean semiring B) adds a twist and a different kind of complexity to the theory.

A Baer ring is said to be Abelian if all its idempotents are central, and (Dedekind) finite if $ xy = 1 $ implies $ yx = 1 $. kinsey auctioneers

"WebThis is the simplest example of a Boolean-like ring which is not also Boolean. Using (9), (1.1) and (1.2), (D) may be restated as: (D') A Boolean-like ring is a commutative ring with unit element in which, for all elements a, b, (10) ab(a Ab) = 3a*. Proof. a+b = ab*Aa*b = a(l-b)+b(l-a)-ab(l-a)(l-b), 3ab = ab(a+b — ab)=ab(aAb). " - Boolean ring examples
