A classification of hull operators in archimedean lattice-ordered groups with unit [PDF]

open access: yesCategories and General Algebraic Structures with Applications, 2020
The category, or class of algebras, in the title is denoted by $\bf W$. A hull operator (ho) in $\bf W$ is a reflection in the category consisting of $\bf W$ objects with only essential embeddings as morphisms.

Complex Intuitionistic Fuzzy Soft Lattice Ordered Group and Its Weighted Distance Measures

open access: yesMathematics, 2020
In recent years, the complex fuzzy set theory has intensified the attention of many researchers. This paper focuses on developing the algebraic structures pertaining to lattice ordered groups and lattice ordered subgroups for complex intuitionistic fuzzy

Hierarchical nanochannels based on rod-coil block copolymer for ion transport and energy conversion

open access: yesGiant, 2021
Designable block copolymer (BCP) membranes are emerging for reverse electrodialysis to capture the salinity gradient energy between seawater and river water. However, present BCP based nanochannels are usually prepared from flexible blocks.

Idempotent 2x2 matrices over linearly ordered abelian groups [PDF]

open access: yesCategories and General Algebraic Structures with Applications
In this paper we study multiplicative semigroups of $2\times 2$ matrices over a linearly ordered abelian group with an externally added bottom element. The multiplication of such a semigroup is defined by replacing addition and multiplication by join and

Partially ordered Grothendieck groups [PDF]

open access: yes, 1985
Motivation for the study of partially ordered abelian groups has come from many different parts of mathematics, for mathematical systems with compatible order and additive (or linear) strlk'ctures are quite common.

Compatible elements in partly ordered groups

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2005
Some conditions equivalent to a strong quasi-divisor property (SQDP) for a partly ordered group G are derived. It is proved that if G is defined by a family of t-valuations of finite character, then G admits an SQDP if and only if it admits a quasi ...

The conjugacy problem and related problems in lattice-ordered groups [PDF]

open access: yes, 2005
We study, from a constructive computational point of view, the techniques used to solve the conjugacy problem in the "generic" lattice-ordered group Aut(R) of order automorphisms of the real line.
