The Clifford semiring congruences on an additive regular semiring [PDF]

open access: yes, 2014
A congruence ρ on a semiring S is called a (generalized)Clifford semiring congruence if S/ρ is a (generalized)Clifford semiring. Here we characterize the (generalized)Clifford congruences on a semiring whose additive reduct is a regular semigroup.

On semisimple semirings

open access: yesCommunications in Algebra, 2020
We investigate ideal-semisimple and congruence-semisimple semirings. We give several new characterizations of such semirings using e-projective and e-injective semimodules. We extend several characterizations of semisimple rings to (not necessarily subtractive) commutative semirings.

PAWS: A Tool for the Analysis of Weighted Systems [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2017
PAWS is a tool to analyse the behaviour of weighted automata and conditional transition systems. At its core PAWS is based on a generic implementation of algorithms for checking language equivalence in weighted automata and bisimulation in conditional ...

*-μ-semirings and *-λ-semirings

open access: yesTheoretical Computer Science, 2005
AbstractWe introduce and study *-μ-semirings and *-λ-semirings which generalize inductive *-semirings and weak inductive *-semirings, respectively. Also, we discuss the semiring of formal power series with coefficients in such a semiring and prove that the semiring of formal power series with coefficients in a weak inductive *-semiring [μ-semiring, λ ...

Semirings of Evidence

open access: yesJournal of Logic and Computation, 2020
AbstractIn traditional justification logic, evidence terms have the syntactic form of polynomials, but they are not equipped with the corresponding algebraic structure. We present a novel semantic approach to justification logic that models evidence by a semiring.

Conditional independence on semiring relations [PDF]

open access: yes, 2023
Conditional independence plays a foundational role in database theory, probability theory, information theory, and graphical models. In databases, conditional independence appears in database normalization and is known as the (embedded) multivalued ...

Residuated Structures Derived from Commutative Idempotent Semirings

open access: yesDiscussiones Mathematicae - General Algebra and Applications, 2019
Since the reduct of every residuated lattice is a semiring, we can ask under what condition a semiring can be converted into a residuated lattice. It turns out that this is possible if the semiring in question is commutative, idempotent, G-simple and ...

Fuzzy soft k−ideals over semiring and fuzzy soft semiring homomorphism [PDF]

open access: yesJournal of Hyperstructures, 2015
In this paper, we introduce the notion of fuzzy soft semirings, fuzzy soft ideals, fuzzy soft k− ideals , k−fuzzy soft ideals over semirings and fuzzy soft semiring homomorphism. We study some of their algebraical properties and properties of homomorphic

Ideal Fuzzy Semiring Atas Level Subset

open access: yes, 2022
Semiring merupakan salah satu perluasan dari ring, dengan cara menghilangan salah satu aksioma pada operasi pertama yaitu aksioma invers. Pada semiring terdapat konsep subsemiring dan ideal dengan kondisi bahwa setiap ideal semiring adalah selalu ...

Elementary Equivalence Versus Isomorphism in Semiring Semantics [PDF]

open access: yes, 2021
We study the first-order axiomatisability of finite semiring interpretations or, equivalently, the question whether elementary equivalence and isomorphism coincide for valuations of atomic facts over a finite universe into a commutative semiring ...
