Interior GE‐Algebras

open access: yesJournal of Mathematics, Volume 2021, Issue 1, 2021., 2021
The concepts of (commutative, transitive, left exchangeable, belligerent, antisymmetric) interior GE‐algebras and bordered interior GE‐algebras are introduced, and their relations and properties are investigated. Many examples are given to support these concepts. A semigroup is formed using the set of interior GE‐algebras.

Preferences in discrete multi-adjoint formal concept analysis [PDF]

open access: yes, 2023
Multi-adjoint concept lattice theory is a general fuzzy approach of formal concept analysis, which has diverse interesting properties. One of them is that it is possible to provide different degrees of preference among the set of objects/attributes ...

Interval-valued algebras and fuzzy logics [PDF]

open access: yes, 2010
In this chapter, we present a propositional calculus for several interval-valued fuzzy logics, i.e., logics having intervals as truth values. More precisely, the truth values are preferably subintervals of the unit interval.

Quasivarieties of Wajsberg hoops [PDF]

open access: yes, 2023
In this paper we deal with quasivarieties of residuated structures which form the equivalent algebraic semantics of a positive frag- ment of some substructural logic.

Why most papers on filters are really trivial (including this one) [PDF]

open access: yes, 2023
The aim of this note is to show that many papers on various kinds of filters (and related concepts) in (subreducts of) residuated structures are in fact easy consequences of more general results that have been known for a long ...

Residuated structures and orthomodular lattices [PDF]

open access: yes, 2021
The variety of (pointed) residuated lattices includes a vast proportion of the classes of algebras that are relevant for algebraic logic, e.g., ℓ-groups, Heyting algebras, MV-algebras, or De Morgan monoids.

Model completions for universal classes of algebras: necessary and sufficient conditions [PDF]

open access: yes, 2021
Necessary and sufficient conditions are presented for the (first-order) theory of a universal class of algebraic structures (algebras) to admit a model completion, extending a characterization provided by Wheeler.

Minimal determinization algorithm for fuzzy automata [PDF]

open access: yes, 2023
The determinization of fuzzy automata is a well-studied problem in theoretical computer science celebrated for its practical applications. Indeed, in the fields of fuzzy discrete event systems, fault diagnosis, clinical monitoring, decision-making ...

Annihilators in Universal Algebras: A New Approach

open access: yesJournal of Mathematics, Volume 2020, Issue 1, 2020., 2020
The purpose of this paper is to study annihilators and annihilator ideals in a more general context; in universal algebras.

Strongly divisible lattices and crystalline cohomology in the imperfect residue field case

open access: yesSelecta Mathematica, 2023
Let $k$ be a perfect field of characteristic $p \geq 3$, and let $K$ be a finite totally ramified extension of $K_0 = W(k)[p^{-1}]$. Let $L_0$ be a complete discrete valuation field over $K_0$ whose residue field has a finite $p$-basis, and let $L = L_0\otimes_{K_0} K$.
