Fuzzy Filter Spectrum of a BCK Algebra

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2011
The notion of fuzzy s-prime filters of a bounded BCK-algebra is introduced. We discuss the relation between fuzzy s-prime filters and fuzzy prime filters.

On the K-theory of the C*-algebra associated with a one-sided shift space; pp. 272–279 [PDF]

open access: yesProceedings of the Estonian Academy of Sciences, 2010
One-sided shift spaces are a special kind of non-invertible topological dynamical system with which one can associate a C*-algebra. We show how to construct the C*-algebra associated with a one-sided shift space as the Cuntz–Pimsner C*-algebra of a C ...

The topological Riesz algebras

open access: yesFilomat, 2022
The multiplicative order convergence was studied and investigated on Riesz algebras. This paper deals with Riesz algebras and different topologies on them. In this paper, we investigate Riesz algebras on which we define various kinds of continuities. We give the relation between them under certain specific conditions.

Topology on Equality Algebras

open access: yesBulletin of the Section of Logic
In this paper, by special upsets on equality algebras, we construct a topology on bounded equality algebras and investigate some of their topological properties, such as Hausdorff, T0-space, T1-space and disconnected.

Levels in algebra and topology [PDF]

open access: yesCommentarii Mathematici Helvetici, 1984
In dieser großen und inhaltsreichen Arbeit werden die Grundlagen eines neuen Zusammenhangs zwischen Algebra und algebraischer Topologie gelegt. [Ein zusammen mit \textit{C. K. Peng} verfaßter Vorläufer gleichen Titels erschien bereits in Bull. Am. Math. Soc., New. Ser. 3, 845--848 (1980; Zbl 0435.10016).] Ausgangspunkt war die Entdeckung, daß die Stufe

Gelfand theorem implies Stone representation theorem of Boolean rings

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1995
Stone Theorem about representing a Boolean algebra in terms of open-closed subsets of a topological space is a consequence of the Gelfand Theorem about representing a B∗- algebra as the algebra of continuous functions on a compact Hausdorff space.

Excitations in strict 2-group higher gauge models of topological phases

open access: yesJournal of High Energy Physics, 2020
We consider an exactly solvable model for topological phases in (3+1) d whose input data is a strict 2-group. This model, which has a higher gauge theory interpretation, provides a lattice Hamiltonian realisation of the Yetter homotopy 2-type topological

Topological UP-algebras

open access: yesDiscussiones Mathematicae - General Algebra and Applications, 2019
In this paper, we introduce the notion of topological UP-algebras and several types of subsets of topological UP-algebras, and prove the generalization of these subsets. We also introduce the notions of quotient topological spaces of topological UP-algebras and topological UP-homomorphisms.

Physical Origin of Temperature Induced Activation Energy Switching in Electrically Conductive Cement

open access: yesAdvanced Science, EarlyView.
The temperature‐induced Arrhenius activation energy switching phenomenon of electrical conduction in electrically conductive cement originates from structural degradation within the biphasic ionic‐electronic conduction architecture and shows percolation‐governed characteristics: pore network opening dominates the low‐percolation regime with downward ...

On Geometric Topological Algebras

open access: yesJournal of Mathematical Analysis and Applications, 1993
The paper under review, one of related works by the author [see also the review above], is influenced by, and subsumed under, a programme of sheaf-theoretic treatment of differential geometry, hence the term ``geometric'' for the algebras in the title.
