Type:
model:article and TEXT
Subject:
Boolean algebras, modal algebras, and Boolean spaces with relations
Language:
English
Description:
In this paper we introduce the class of Boolean algebras with an operator between the algebra and the set of ideals of the algebra. This is a generalization of the Boolean algebras with operators. We prove that there exists a duality between these algebras and the Boolean spaces with a certain relation. We also give some applications of this duality.
