BOOLEAN-VALUED ALGEBRAS

Mathematics of the USSR-Sbornik, 1973
The paper contains the construction of a general theory of Boolean-valued algebras: There are introduced the notions of a homeomorphism, congruence, subalgebra and direct product. It is shown that these algebras possess properties that are totally analogous to the properties of two-valued algebras.

On the Representation of Boolean Algebras

Canadian Mathematical Bulletin, 1962
Let B be a Boolean algebra and let ℳ and n be two systems of subsets of B, both containing all finite subsets of B. Let us assume further that the join ∨M of every set M∊ℳ and the meet ∧N of every set N∊n exist.

A Representation for Boolean Algebras

American Journal of Mathematics, 1951
1. The content. The success of Stone [5] in representing Boolean algebras by fields of sets leads one to search for other representations. (See also [2, p. 159], [4].) Using splitting endomorphisms on a type of Abelian group with an order relation, we are led to a faithful representation of a given Boolean algebra B. The group employed will be called a

Hierarchies of Boolean algebras

Journal of Symbolic Logic, 1970
A denumerable structure is said to be recursive iff its universe is a recursive subset of the natural numbers and its relations and operations are recursive. For example, the standard model of number theory is recursive. A structure is said to be recursively presentable iff it is isomorphic to a recursive structure.

Parallel Processing in Boolean Algebra

IEEE Transactions on Computers, 1972
A processor called Boolean analyzer has been presented at the 1968 IFIP Congress to introduce parallel processing of Boolean expressions [1]. The present paper shows how to increase its speed many times by making its processing more parallel. The applications of the Boolean analyzer are limited to few but important problems.
