On the injectivity of Boolean algebras [PDF]

, 1993
summary:The functor taking global elements of Boolean algebras in the topos $\text{$\bold{Sh}\frak B$}$ of sheaves on a complete Boolean algebra $\frak B$ is shown to preserve and reflect injectivity as well as completeness. This is then used to derive a

A Cantor-Bernstein theorem for $\sigma$-complete MV-algebras

, 2003
summary:The Cantor-Bernstein theorem was extended to $\sigma $-complete boolean algebras by Sikorski and Tarski. Chang’s MV-algebras are a nontrivial generalization of boolean algebras: they stand to the infinite-valued calculus of Łukasiewicz as boolean

On annihilators in BL-algebras

Open Mathematics, 2016
In the paper, we introduce the notion of annihilators in BL-algebras and investigate some related properties of them. We get that the ideal lattice (I(L), ⊆) is pseudo-complemented, and for any ideal I, its pseudo-complement is the annihilator I⊥ of I ...

Implementing multidomain non‐pharmaceutical interventions for preventing cognitive decline in community‐dwelling older adults in China: An embedded mixed‐methods implementation study of determinants and strategies

Alzheimer's &Dementia, Volume 22, Issue 6, June 2026.
Abstract INTRODUCTION The WW‐FINGERS network has demonstrated the efficacy of multidomain non‐pharmaceutical interventions (NPIs) but left their real‐world implementation largely unexplored, prompting this study in Changxing County to identify key determinants and develop actionable strategies for community‐based delivery.

Text Mining in Bibliometrics and Science Mapping: A Methodological Review

WIREs Computational Statistics, Volume 18, Issue 2, June 2026.
Text mining has become a foundational component of contemporary bibliometrics and science mapping, enabling systematic analysis of the semantic structure, thematic evolution, and cognitive organization of scientific fields. Integrating textual evidence with relational indicators enriches knowledge maps and supports more comprehensive, content‐sensitive

Component graphs of vector spaces and zero-divisor graphs of ordered sets

AKCE International Journal of Graphs and Combinatorics
In this paper, nonzero component graphs and nonzero component union graphs of finite-dimensional vector spaces are studied using the zero-divisor graph of a specially constructed 0–1-distributive lattice and the zero-divisor graph of rings.

Complete and atomic Tarski algebras

, 2019
Tarski algebras, also known as implication algebras or semi-boolean algebras, are the {→}-subreducts of Boolean algebras. In this paper we shall introduce and study the complete and atomic Tarski algebras.
