Revisiting the Representation Theorem of Finite Distributive Lattices with Principal Congruences. A Proof-By-Picture Approach

open access: yesDiscussiones Mathematicae - General Algebra and Applications, 2021
A classical result of R.P. Dilworth states that every finite distributive lattice D can be represented as the congruence lattice of a finite lattice L. A sharper form was published in G. Grätzer and E.T.

n-Fold Fantastic and n-Fold Involutive Ideals in Bounded Commutative Residuated Lattices

open access: yesDiscussiones Mathematicae - General Algebra and Applications, 2022
In this paper, we introduce the concepts of n-fold obstinate ideals, n-fold normal ideals, n-fold fantastic ideals and n-fold involutive ideals in residuated lattices, state and prove some of their properties.

Rough sets based on fuzzy ideals in distributive lattices

open access: yesOpen Mathematics, 2020
In this paper, we present a rough set model based on fuzzy ideals of distributive lattices. In fact, we consider a distributive lattice as a universal set and we apply the concept of a fuzzy ideal for definitions of the lower and upper approximations in ...

Applying the Czédli-Schmidt Sequences to Congruence Properties of Planar Semimodular Lattices

open access: yesDiscussiones Mathematicae - General Algebra and Applications, 2021
Following Grätzer and Knapp, 2009, a planar semimodular lattice L is rectangular, if the left boundary chain has exactly one doubly-irreducible element, cl, and the right boundary chain has exactly one doubly-irreducible element, cr, and these elements ...

The Cayley Sum Graph of Ideals of a Lattice

open access: yesDiscussiones Mathematicae - General Algebra and Applications, 2020
Let L be a lattice, 𝒥(L) be the set of ideals of L and S be a subset of 𝒥 (L). In this paper, we introduce an undirected Cayley graph of L, denoted by ΓL,S with elements of 𝒥 (L) as the vertex set and, for two distinct vertices I and J, I is adjacent to ...

Prime preideals on bounded EQ-algebras

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2022
EQ-algebras were introduced by Novák in [14] as an algebraic structure of truth values for fuzzy type theory (FFT). In [1], Borzooei et. al. introduced the notion of preideal in bounded EQ-algebras.

Stone Commutator Lattices and Baer Rings

open access: yesDiscussiones Mathematicae - General Algebra and Applications, 2022
In this paper, we transfer Davey‘s characterization for κ -Stone bounded distributive lattices to lattices with certain kinds of quotients, in particular to commutator lattices with certain properties, and obtain related results on prime, radical ...

On Various 2-absorbing prime ideals in non commutative rings

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2023
In this paper we analyze strongly 2-absorbing prime ideals (shortly strongly 2-API), strongly 2-absorbing weak prime ideals (shortly strongly 2-AWPI) and 2-absorbing weak prime ideals (shortly 2-AWPI) in a non-commutative ring, which represent ...

On n‐fold implicative filters of lattice implication algebras

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 26, Issue 11, Page 695-699, 2001., 2001
We introduce the notion of n‐fold implicative filters and n‐fold implicative lattice implication algebras. We give characterizations of n‐fold implicative filters and n‐fold implicative lattice implication algebras. Finally, we construct an extension property for n‐fold implicative filter.

Weak-hyperlattices derived from fuzzy congruences

open access: yesDiscussiones Mathematicae - General Algebra and Applications, 2017
In this paper we explore the connections between fuzzy congruence relations, fuzzy ideals and homomorphisms of hyperlattices. Indeed, we introduce the concept of fuzzy quotient set of hyperlattices as it was done in the case of rings [19].
