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 ...

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.

Thermodynamic semirings

open access: yesJournal of Noncommutative Geometry, 2014
The Witt construction describes a functor from the category of Rings to the category of characteristic 0 rings. It is uniquely determined by a few associativity constraints which do not depend on the types of the variables considered, in other words, by integer polynomials.

Metrization of idempotent semiring of topological rings

open access: yesApplied General Topology
In this paper, we have introduced natural H+ - pseudovaluation and  H+ -norm on a completely regular semiring making it a topological completely regular (algebraic) semiring and established some necessary and sufficient conditions of metrizability of a ...

Causal analysis of extreme risk in a network of industry portfolios

open access: yesCanadian Journal of Statistics, Volume 54, Issue 1, March 2026.
Abstract We provide a detailed review of causal dependence within the framework of max‐linear structural models. Such models express each node variable as a max‐linear function of its parental node variables in a directed acyclic graph (DAG) and some exogenous innovation.

Ideal basis in constructions defined by directed graphs

open access: yesElectronic Journal of Graph Theory and Applications, 2015
The present article continues the investigation of visible ideal bases in constructions defined using directed graphs. This notion is motivated by its applications for the design of classication systems.

Singularist Semirealism [PDF]

open access: yesThe British Journal for the Philosophy of Science, 2013
Abstract: This paper proposes to carve out a new position in the scientific realism/antirealism debate and argue that it captures some of the most important realist and some of the most important antirealist considerations. The view, briefly stated, is that there is always a fact of the matter about whether the singular statements science gives us are ...

On Γ-Semiring With Identity

open access: yesDiscussiones Mathematicae - General Algebra and Applications, 2017
In this paper we study the properties of structures of the semigroup (M,+) and the Γ-semigroup M of Γ -semiring M and regular Γ-semiring M satisfying the identity a + aαb = a or aαb + a = a or a + aαb + b = a or a + 1 = 1, for all a ∈ M, α ∈ Γ.

Pseudo‐Quantum Fractional Calculus and Existence of Solutions for Delay Pseudo‐Fractional Differential Equations in Generalized Banach Spaces

open access: yesJournal of Mathematics, Volume 2026, Issue 1, 2026.
This paper presents a new framework of pseudo‐q–fractional calculus in generalized Banach spaces by bringing together pseudo‐analysis, G–calculus, and quantum calculus. We introduce Liouville–Caputo and Riemann–Liouville pseudo‐q–fractional operators and outline their main properties. Then, by applying the Banach fixed point principle, we establish the
