Closure Operations on Intuitionistic Linear Algebras

open access: yesAnnales Mathematicae Silesianae
In this paper, we introduce the notions of radical filters and extended filters of Intuitionistic Linear algebras (IL-algebras for short) and give some of their properties.

On residuated skew lattices

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2019
In this paper, we define residuated skew lattice as non-commutative generalization of residuated lattice and investigate its properties. We show that Green’s relation 𝔻 is a congruence relation on residuated skew lattice and its quotient algebra is a ...

Finite Distributive Concept Algebras [PDF]

open access: yes, 2018
Concept algebras are concept lattices enriched by a weak negation and a weak opposition. In Ganter and Kwuida (Contrib. Gen. Algebra, 14:63-72, 2004) we gave a contextual description of the lattice of weak negations on a finite lattice.

Notes on the representation of Distributive Modal Algebras

open access: yes, 2008
In this work we give some results on the representation by means of relational structures of distributive lattices endowed with two modal operators and Þ, and two weak forms of negation and r. 2000 Mathematics Subject Classification: Primary 03G10, 06D05,

On residuated n-lattice

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica
In this paper, we introduce residuated n-lattice: a variety of residuated semigroup equipped with binary hyperoperations n-sup and n-inf. We define the left bound, right bound, n-supremum, n-infimum, maximum and minimum with respect to it′s relation.

Convergences in perfect BL-algebras [PDF]

open access: yes, 2007
The aim of the paper is to investigate some concepts of convergence in the class of perfect BL-algebras. Similarity convergence was developed by G. Georgescu and A.

Applications of Contractive-like Mapping Principles to Fuzzy Equations [PDF]

open access: yes
We recall a recent extension of the classical Banach fixed point theorem to partially ordered sets and justify its applicability to the study of the existence and uniqueness of solution for fuzzy and fuzzy differential equations.

The existence of one-point connectifications

open access: yes, 2017
P. Alexandroff proved that a locally compact $T_2$-space has a $T_2$ one-point compactification (obtained by adding a "point at infinity") if and only if it is non-compact.

A Note on Direct Products, Subreducts and Subvarieties of PBZ*--lattices

open access: yes, 2019
PBZ*--lattices are bounded lattice--ordered structures arising in the study of quantum logics, which include orthomodular lattices, as well as antiortholattices.
