The variety of boolean semirings
WebGiven a class of idempotent semirings, one can regard it as a class of type (2, 2) algebra satisfying two additional identities x x ˇ x and x C x ˇ x. Thus, the class of all idempotent semirings is an equational class, or equivalently a variety. We denote this variety of all idempotent semirings by I. A special subvariety of the variety I is Webit is proved that the semiring variety generated by a finite number of finite fields with pairwise distinct characteristics and distributive lattices are finitely based. As we know, the “simplest” semiring variety generated by finite fields and distributive lattices is the the variety of Boolean semirings generated by B2 and

WebSemirings are modifications of unitary rings where the additive reduct does not form a group in general, but only a monoid. We characterize multiplicatively idempotent semirings and Boolean rings as semirings satisfying particular identities. Further, we work with varieties of enriched semirings. We show that the variety of enriched multiplicatively idempotent … WebIt is well known that the variety of Boolean semirings, which is generated by the three element semiring S, is dual to the category of partially Stone spaces. We place arXiv:0801.4923v1 [math.CT] 31 Jan 2008 this duality in the context of natural dualities.

WebEilenberg’s variety theorem, a centerpiece of algebraic automata theory, establishes a bijective correspondence between varieties of languages and pseudovarieties of monoids. ... semigroups, or semirings. A major result concerns varieties of languages. These are classes of regular languages closed under. boolean operations (union ... WebMSO-logic are representable by weighted automata. Locally finite semirings were investigated in [6]; they form a large class of semirings including e.g. all finite semirings, the max-min-semiring employed for capacity problems of networks, and all Boolean algebras. Thus we obtain Bu¨chi’s and Elgot’s theorems as a particular consequence.
