Mathematical Logic Quarterly, 1993
AbstractThe purpose of this paper is to define and investigate the new class of quasi‐Stone algebras (QSA's). Among other things we characterize the class of simple QSA's and the class of subdirectly irreducible QSA's. It follows from this characterization that the subdirectly irreducible QSA's form an elementary class and that the variety of QSA's is ...

Definable sets in Stone algebras
Archive for Mathematical Logic, 2016The paper deals with definable sets of Stone algebras. The authors introduce the notion of pseudo o-minimality of a lattice-ordered structure and prove that the completion of the theory of Stone algebras is pseudo o-minimal. Thy also investigate the decomposition of Stone algebras and prove that any definable set of a Stone algebra is a union of ...

Suppose \(A\) is a \(C^*\)-algebra and let \(M(A)\) be its multiplier algebra. A linear mapping \(T\) defined on a dense subspace of \(A\) is said to be affiliated with \(A\), if there exists a multiplier \(z\in M(A)\), \(\| z\|\leq 1\) such that \(T[(1- z^* z)^{{1\over 2}} a]= za\), \(\forall a\in A\). Theorem.

The structure of algebraically and existentially closed Stone and double Stone algebras
Journal of Symbolic Logic, 1989In this paper we study the varieties of Stone algebras (S, ∧, ∨, *, 0, 1) and double Stone algebras (D, ∧, ∨, *, +, 0, 1). Our primary interest is to give a structural description of the algebraically and existentially closed members of both classes. Our technique is an application of the natural dualities of Davey [6] and Clark and Krauss [5].

On a common abstraction of de Morgan algebras and Stone algebras
Proceedings of the Royal Society of Edinburgh: Section A Mathematics, 1983SynopsisWe consider a common abstraction of de Morgan algebras and Stone algebras which we call an MS-algebra. The variety of MS-algebras is easily described by adjoining only three simple equations to the axioms for a bounded distributive lattice.
