Complete intersection lattice ideals

open access: yesJournal of Algebra, 2005
In this paper we completely characterize lattice ideals that are complete intersections or equivalently complete intersections finitely generated semigroups of $\bz^n\oplus T$ with no invertible elements, where $T$ is a finite abelian group. We also characterize the lattice ideals that are set-theoretic complete intersections on binomials.

On certain Wallman spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1994
Several generalized Wallman type spaces are considered as well as various lattices of subsets therein. In particular, regularity of these lattices and consequences are investigated.

On Bonds for Generalized One-Sided Concept Lattices

open access: yesMathematics, 2021
The generalized one-sided concept lattices represent a generalization of the classical FCA method convenient for a hierarchical analysis of object-attribute models with different types of attributes.

A complete lattice technicolor model [PDF]

open access: yesInternational Journal of Modern Physics A, 2014
We construct a lattice gauge theory using reduced staggered fermions and gauge fields which provides a nonperturbative realization of a complete technicolor model; one which treats both strong and weakly coupled gauge sectors on an equal footing. We show that the model is capable of developing a Higgs phase at nonzero lattice spacing via the formation

Free completely distributive lattices [PDF]

open access: yesProceedings of the American Mathematical Society, 1979
We show that the usual construction of the free distributive lattice on n generators generalizes to an arbitrary quantity of generators and actually yields a free completely distributive lattice. Furthermore, for an infinite number of generators the cardinality of the corresponding free completely distributive lattice is exactly that of the power set ...

Reflective Full Subcategories of the Category of L-Posets

open access: yesAbstract and Applied Analysis, 2012
This paper focuses on the relationship between L-posets and complete L-lattices from the categorical view. By considering a special class of fuzzy closure operators, we prove that the category of complete L-lattices is a reflective full subcategory of ...

On the positive weak almost limited operators

open access: yesArab Journal of Mathematical Sciences, 2015
Using the concept of approximately order bounded sets with respect to a lattice seminorm, we establish some new characterizations of positive weak almost limited operators on Banach lattices.

Semi-Overlap Functions on Complete Lattices, Semi-Θ-Ξ Functions, and Inflationary MTL Algebras

open access: yesAxioms
As new kinds of aggregation functions, overlap functions and semi overlap functions are widely applied to information fusion, approximation reasoning, data classification, decision science, etc.

The Fixed Point Property for Intuitionistic Fuzzy Lattices

open access: yesFuzzy Information and Engineering, 2017
In this paper, based on the concept of intuitionistic fuzzy lattice previously introduced by Tripathy and his colleagues, a class of intuitionistic fuzzy complete lattices is proposed with some interesting characterizations given.

On Aggregations of Algebraic Objects in Data Modeling

open access: yesMathematics
Aggregation operators are mathematical tools that, under certain constraints in the form of properties imposed on those mathematical functions, provide a representative value for the whole set of input values or structures.
