Essential extensions of stone algebras
Algebra Universalis, 1977A distributive \(p\)-algebra \(\langle L;\cup,\cap,*,0,1\rangle\) (see the review of [the author, Algebra Univers. 7, 265--271 (1977; Zbl 0358.06026)]) is called a Stone algebra if \(L\) satisfies the identity \(x^*\cup x^{**} =1\). In the paper the essential extensions of Stone algebras are characterized, which improves an earlier result of \textit{H.

We study a generalisation of relation algebras in which the underlying Boolean algebra structure is replaced with a Stone algebra. Many theorems of relation algebras generalise with no or small changes. Weighted graphs represented as matrices over extended real numbers form an instance.

On the Triple Characterization for Stone Algebras
Canadian Journal of Mathematics, 1975In [1], C. C. Chen and G. Grâtzer developed a method for studying Stone algebras by associating with each Stone algebra L, a uniquely determined triple (C(L), D(L), ɸ (L)), consisting of a Boolean algebra C(L), a distributive lattice D(L), and a connecting map ɸ(L).

Quantifier elimination for Stone algebras
Archive for Mathematical Logic, 1989A Stone algebra is a distributive lattice with pseudocomplement that satisfies the Stone identity \(a^*\sqcup a^{**}=1\). The author determines all quantifier elimination classes of Stone algebras and all classes of Stone algebras that admit positive quantifier elimination (i.e.

Priestley Duality for Quasi-Stone Algebras
Studia Logica, 2000The author describes the Priestley space of a quasi-Stone algebra in terms of a Priestley space with a certain equivalence relation. He shows that finite quasi-Stone algebras enjoy the amalgamation property and describes the Priestley space for free quasi-Stone algebras over a finite set.

De Morgan Algebras with a Quasi-Stone Operator
Studia Logica, 2013In this work, the class of those algebras \((L;^{\circ} ,^{\ast})\) is investigated where \((L;^{\circ})\) is a De Morgan algebra, \((L;^{\ast})\) is a quasi-Stone algebra, and the unary operations \(x\longrightarrow x^{\circ}\) and \(x\longrightarrow x^{\ast}\) satisfy the identity \(x^{\ast\ast\circ}=x^{\ast\circ\ast}\).

Post-like algebras and injective Stone algebras
Algebra Universalis, 1975In [3] Balbes and Grw gave intrinsic and extrinsic characterizations of injective Stone algebras. Specifically, the injectives can be characterized (extrinsically) as those Stone algebras that are the direct product of a complete Boolean algebra with a complete Post algebra of order three.
