A domain-theoretic investigation of posets of sub-sigma-algebras (extended abstract) [PDF]

Electronic Proceedings in Theoretical Computer Science, 2010
Given a measurable space (X, M) there is a (Galois) connection between sub-sigma-algebras of M and equivalence relations on X. On the other hand equivalence relations on X are closely related to congruences on stochastic relations.

New directions in general fuzzy automata: a dynamic-logical view [PDF]

AUT Journal of Mathematics and Computing, 2020
In the current study, by a general fuzzy automaton we aim at showing a set of propositions related to a given automaton showing that the truth-values are depended on thestates, inputs and membership values of active states at time t.

Improving the efficiency of using multivalued logic tools: application of algebraic rings

Scientific Reports, 2023
It is shown that in order to increase the efficiency of using methods of abstract algebra in modern information technologies, it is important to establish an explicit connection between operations corresponding to various varieties of multivalued logics ...

Self-Dual Normal Basis of a Galois Ring

Journal of Mathematics, 2014
Let R′=GR(ps,psml) and R=GR(ps,psm) be two Galois rings. In this paper, we show how to construct normal basis in the extension of Galois rings, and we also define weakly self-dual normal basis and self-dual normal basis for R′ over R, where R′ is ...

The Order of Hypersubstitutions of Type (2,1)

International Journal of Mathematics and Mathematical Sciences, 2011
Hypersubstitutions are mappings which map operation symbols to terms of the corresponding arities. They were introduced as a way of making precise the concept of a hyperidentity and generalizations to 𝑀-hyperidentities.

The minimal closed monoids for the Galois connection ${\rm End}$-${\rm Con}$ [PDF]

Mathematica Bohemica
The minimal nontrivial endomorphism monoids $M={\rm End}{\rm Con} (A,F)$ of congruence lattices of algebras $(A,F)$ defined on a finite set $A$ are described.

Global Solvably Closed Anabelian Geometry [PDF]

, 2006
In this paper, we study the pro-Σ anabelian geometry of hyperbolic curves, where Σ is a nonempty set of prime numbers, over Galois groups of “solvably closed extensions” of number fields — i.e., infinite extensions of number fields which have ...

ESSENTIAL AND RETRACTABLE GALOIS CONNECTIONS [PDF]

Journal of Algebra and Its Applications, 2013
For bounded lattices, we introduce certain Galois connections, called (cyclically) essential, retractable and UC Galois connections, which behave well with respect to concepts of module-theoretic nature involving essentiality. We show that essential retractable Galois connections preserve uniform dimension, whereas essential retractable UC Galois ...
