WitrynaClosed semirings are algebraic structures that provide a unified approach to a number of seemingly unrelated problems of computer science and operations research. For example, semirings can be used to describe the algebra related to regular expressions, graph-theoretical path problems, and linear equations. We present a new axiomatic ... Witrynacommutative semirings are forced by certain expected iden-tities in RA. Having identiﬁed commutative semirings as the right algebraic structure, we argue that a symbolic rep- ... closed under RAqueries, and the main result of [19] is an algorithm for answering RAqueries on c-tables, producing another c-table as a result.

We call a semiring S locally closed if for all a ∈ S there is some integer k such that 1 + a + ⋯ + ak =1 + a + ⋯ + ak + 1.

WitrynaIn abstract algebra, a semiring is an algebraic structure similar to a ring, but without the requirement that each element must have an additive inverse.. The term rig is also used occasionally —this originated as a joke, suggesting that rigs are rings without negative elements, similar to using rng to mean a ring without a multiplicative identity. ...

We give a generic algorithm for ﬁnding single-source shortest distances in a weighted directed graph when the weights satisfy the conditions of our general semiring framework.

WitrynaA derivation d of a ring R is said to be locally nilpotent if for any x ∈ R, there exists a positive inte-ger n such that dn(x)= 0. Locally nilpotent derivations play an important role in commutative alge-bra and algebraic geometry, and several problems may be formulated using locally nilpotent derivations (see Essen, 1995; Ferrero, 1992). Witryna8 lip 2008 · We give a sufficient condition which ensures that a semiring with an idempotent addition is inherently nonfinitely based. This enables us to provide a number of small and natural examples of nonfinitely based semirings, including semirings of binary relations on a finite set. suzuki uh 125 service manualWitryna15 lis 2007 · A ∗–λ-semiring is an ordered semiring S equipped with a star operation such that for any a, b ∈ S, a ∗ b is the least fixed point of the linear mapping x ↦ ax + b … suzuki uh 200 service manual

A subset A of a topological space is called locally closed is it is open in its closure, or equivalently if it is the intersection of a closed set with an open set. This terminology seems to be standard (e.g. Encyclopedia of Mathematics ). However, I don't understand why this property has the name "locally closed".

Witrynaa locally ﬁnite semiring with a deﬁned behaviour is equivalent to a one-way automaton. In Section 2, we consider locally ﬁnite semirings. In particular, we study how the additive order allows to encode inﬁnite sums. In Section 3, we introduce weighted two-way automata over locally ﬁnite semirings and we show that they

The study of derivations of prime ring was initiated by Posner ().Posner considered the composition of derivations and showed that the composition of two nonzero derivations of a prime ring R cannot be a derivation provided that characteristic of R is different from 2.
