On Boolean algebras which have the Vitali-Hahn-Saks property
Le Matematiche, 1997 Given a boolean algebra A, we say when A verifies the Drewnowski condition. In thepaper we prove that if a boolean algebra verifies the Drewnowski condition then A has the Vitali-Hahn-Saks property. Also other related questions are investigated.

Reflexive algebras and sigma algebras
International Journal of Mathematics and Mathematical Sciences, 1986 The concept of a reflexive algebra (σ-algebra) β of subsets of a set X is defined in this paper. Various characterizations are given for an algebra (σ-algebra) β to be reflexive.

Nanofluidic Spiking Logics Solves Linearly Inseparable and Separable Tasks
Advanced Computing, Volume 1, Issue 1, December 2026.This work reports the biomimetic nanofluidic spiking logics capable of solving both linearly inseparable and separable tasks. By emulating the non‐monotonic and monotonic activation functions of biological ion channels, it can not only perform linearly separable AND and OR operations, but also implement the linearly inseparable XOR task, an ...

, 2017 This chapter discusses how Boole cast logic into algebraic form. Boole was interested in symbolic analysis years before he wrote his Laws of Thought. In fact, others before him—in particular, the German mathematician Gottfried Wilhelm Leibniz (1646–1716)—

Gődel filters in residuated lattices
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2021 In this paper, in the spirit of [4], we study a new type of filters in residuated lattices : Gődel filters. So, we characterize the filters for which the quotient algebra that is constructed via these filters is a Gődel algebra and we establish the ...

A typology for inclusive mathematics education practices
Support for Learning, Volume 41, Issue 4, November 2026.Abstract This paper examines Inclusive Mathematics Education (IME) practices for students with Special Educational Needs (SEN) in upper primary and lower post‐primary settings. In response to the absence of shared conceptualisations of SEN and IME, the study adopts a conceptual research design and develops a typology grounded in analysis of existing ...

Completeness for the coalgebraic cover modality [PDF]
Logical Methods in Computer Science, 2012 We study the finitary version of the coalgebraic logic introduced by L. Moss. The syntax of this logic, which is introduced uniformly with respect to a coalgebraic type functor, required to preserve weak pullbacks, extends that of classical propositional

Precision Restoration to Minimize Soil Loss in a Watershed in the Atlantic Forest Domain
Land Degradation &Development, Volume 37, Issue 15, Page 10585-10599, September 2026.ABSTRACT The Turvo River Watershed, located in the Zona da Mata region of Minas Gerais and part of the Doce River Basin, faces serious problems of erosion and soil degradation, which compromise and reduce the quality of local water resources. Given this scenario, it is essential to implement environmental recovery strategies that prioritize the ...
