Overlap Algebras: a Constructive Look at Complete Boolean Algebras [PDF]

open access: diamondLogical Methods in Computer Science, 2020
The notion of a complete Boolean algebra, although completely legitimate in constructive mathematics, fails to capture some natural structures such as the lattice of subsets of a given set.

Some Properties of Complete Boolean Algebras

open access: greenSahand Communications in Mathematical Analysis, 2021
Summary: The main result of this paper is a characterization of the strongly algebraically closed algebras in the lattice of all real-valued continuous functions and the equivalence classes of \(\lambda\)-measurable. We shall provide conditions which strongly algebraically closed algebras carry a strictly positive Maharam submeasure.

Complete Boolean Algebras are Bousfield Lattices [PDF]

open access: green, 2018
Given a complete Heyting algebra we construct an algebraic tensor triangulated category whose Bousfield lattice is the Booleanization of the given Heyting algebra. As a consequence we deduce that any complete Boolean algebra is the Bousfield lattice of some tensor triangulated category.

Boolean-valued equivalence relations and complete extensions of complete boolean algebras [PDF]

open access: diamondBulletin of the Australian Mathematical Society, 1970
It is remarked that, if A is a complete boolean algebra and δ is an A-valued equivalence relation on a non-empty set I, then the set of δ-extensional functions from I to A can be regarded as a complete boolean algebra extension of A and a characterization is given of the complete extensions which arise in this way.
