Towards a generalisation of formal concept analysis for data mining purposes [PDF]
, 2006 In this paper we justify the need for a generalisation of Formal Concept Analysis for the purpose of data mining and begin the synthesis of such theory.

Annihilators in Universal Algebras: A New Approach
Journal 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.

Generalized Hesitant Fuzzy Ideals in Semigroups
Journal of Mathematics, Volume 2020, Issue 1, 2020., 2020 In this paper, as a generalization of the concepts of hesitant fuzzy bi‐ideals and hesitant fuzzy right (resp. left) ideals of semigroups, the concepts of hesitant fuzzy (m, n)‐ideals and hesitant fuzzy (m, 0)‐ideals (resp. (0, n)‐ideals) are introduced.

The Reticulation of a Universal Algebra [PDF]
, 2017 The reticulation of an algebra $A$ is a bounded distributive lattice ${\cal L}(A)$ whose prime spectrum of filters or ideals is homeomorphic to the prime spectrum of congruences of $A$, endowed with the Stone topologies.

The Relations between Residuated Frames and Residuated Connections
Mathematics, 2020 We introduce the notion of (dual) residuated frames as a viewpoint of relational semantics for a fuzzy logic. We investigate the relations between (dual) residuated frames and (dual) residuated connections as a topological viewpoint of fuzzy rough sets ...

Coalgebraic completeness-via-canonicity for distributive substructural logics [PDF]
, 2016 We prove strong completeness of a range of substructural logics with respect to a natural poset-based relational semantics using a coalgebraic version of completeness-via-canonicity.

ℒ-Fuzzy Ideals of Residuated Lattices
Discussiones Mathematicae - General Algebra and Applications, 2019 This paper mainly focuses on building the ℒ-fuzzy ideals theory of residuated lattices. Firstly, we introduce the notion of ℒ-fuzzy ideals of a residuated lattice and obtain their properties and equivalent characterizations. Also, we introduce the notion

Kernels of Residuated Maps as Complete Congruences in Lattices
International Journal of Computational Intelligence Systems, 2020 In a context of lattice-valued functions (also called lattice-valued fuzzy sets), where the codomain is a complete lattice L, an equivalence relation defined on L by the equality of related cuts is investigated.

When does a semiring become a residuated lattice [PDF]
, 2016 It is an easy observation that every residuated lattice is in fact a semiring because multiplication distributes over join and the other axioms of a semiring are satisfied trivially. This semiring is commutative, idempotent and simple.
