Completions of Boolean algebras with partially additive operators

Yen-Yi Wu

Vol. 40 (1972), No. 3, 753–758
Abstract

To generalize a result of Jónsson and Tarski on perfect extensions of Boolean algebras with operators, L. Henkin has introduced the notion of p-additive operation for p a positive integer. Here we use this notion to extend the analogous result of D. Monk which states that each equation without occurrences of the complementation sign has its validity preserved when passing from a Boolean algebra with operators to its completion.
