Free Distributive Completions of Partial Complete Lattices

Order, 1997
First the author gives some basic definitions and further provides a description of embedding of partial complete lattices in suitable concept lattices and its use in concept exploration. He discusses in which sense these concept lattices are freely generated by the partial complete lattices ``in the most distributive way''.

Definable Operators on Stable Set Lattices

Studia Logica: An International Journal for Symbolic Logic, 2020
A fundamental result from Boolean modal logic states that a first-order definable class of Kripke frames defines a logic that is validated by all of its canonical frames.

Prime, irreducible, and completely irreducible lattice preradicals on modular complete lattices (I)

Journal of Algebra and Its Applications, 2021
Based on the concept of a lattice preradical recently introduced in [T. Albu and M. Iosif, Lattice preradicals with applications to Grothendieck categories and torsion theories, J. Algebra 444 (2015) 339–366], we present and investigate in this paper, the latticial counterparts of the concepts of prime and irreducible preradicals on the category Mod ...

Completeness in Semi-Lattices

Canadian Journal of Mathematics, 1957
Let (X, ≤) be a partially ordered set, that is, X is a set and ≤ is a reflexive, anti-symmetric, transitive, binary relation on X.We write,for each x ∈ X. If, moreover,exists for each x and y in X, then (X, ≤) is said to be a semi-lattice.

Fuzzy complete lattices

Fuzzy Sets and Systems, 2009
The authors present an approach to fuzzification of complete lattices, which is a special kind of complete \(\Omega\)-lattices defined by Lai and Zhang. Tarski fixed-point theorem for the \(L\)-fuzzy complete lattices was proved in a different way. Some fuzzy powerset operators are suggested.

Lattice complete graphs

Journal of Applied and Industrial Mathematics, 2017
Summary: We study the properties of graphs that can be placed in a rectangular lattice so that all vertices located in the same (horizontal or vertical) row be adjacent. Some criterion is formulated for an arbitrary graph to be in the specified class.
