A general framework for product representations: bilattices and beyond

open access: yes, 2015
This paper studies algebras arising as algebraic semantics for logics used to model reasoning with incomplete or inconsistent information. In particular we study, in a uniform way, varieties of bilattices equipped with additional logic-related operations

On sets of graded attribute implications with witnessed non-redundancy

open access: yes, 2015
We study properties of particular non-redundant sets of if-then rules describing dependencies between graded attributes. We introduce notions of saturation and witnessed non-redundancy of sets of graded attribute implications are show that bases of ...

A note on operations of hesitant fuzzy sets [PDF]

open access: yesInternational Journal of Computational Intelligence Systems, 2015
In this paper, properties of operations and algebraic structures of hesitant fuzzy sets are investigated. Semilattices of hesitant fuzzy sets with union and intersection are discussed, respectively.

$L$-biconvex sets on some fuzzy algebraic substructures

open access: yesAIMS Mathematics, 2020
With a complete residuated lattice $L$ as the set of truth values, we first introduce the concept of $L$-biconvex sets. Then we focus on investigating the forms of $L$-biconvex sets on three fuzzy algebraic substructures which are $L$-subsemilattices, $L$

Set optimization - a rather short introduction

open access: yes, 2014
Recent developments in set optimization are surveyed and extended including various set relations as well as fundamental constructions of a convex analysis for set- and vector-valued functions, and duality for set optimization problems.

Vague Filters of Residuated Lattices [PDF]

open access: yesJournal of Discrete Mathematics, 2014
Notions of vague filters, subpositive implicative vague filters, and Boolean vague filters of a residuated lattice are introduced and some related properties are investigated. The characterizations of (subpositive implicative, Boolean) vague filters is obtained. We prove that the set of all vague filters of a residuated lattice forms a complete lattice

Some Applications of Fuzzy Sets in Residuated Lattices

open access: yesAxioms
Many papers have been devoted to applying fuzzy sets to algebraic structures. In this paper, based on ideals, we investigate residuated lattices from fuzzy set theory, lattice theory, and coding theory points of view, and some applications of fuzzy sets ...

New topology in residuated lattices

open access: yesOpen Mathematics, 2018
In this paper, by using the notion of upsets in residuated lattices and defining the operator Da(X), for an upset X of a residuated lattice L we construct a new topology denoted by τa and (L, τa) becomes a topological space.

The Lattice of Intuitionistic Fuzzy Filters in Residuated Lattices

open access: yesJournal of Applied Mathematics, 2014
The notion of tip-extended pair of intuitionistic fuzzy filters is introduced by which it is proved that the set of all intuitionistic fuzzy filters in a residuated lattice forms a bounded distributive lattice.
