A Simultaneous Generalization of Independence and Disjointness in Boolean Algebras [PDF]

open access: yesOrder, 2011
We give a definition of some classes of boolean algebras generalizing free boolean algebras; they satisfy a universal property that certain functions extend to homomorphisms. We give a combinatorial property of generating sets of these algebras, which we call n-independent.

Algebraic representation of generalized boolean algebras

open access: yes, 2018
The main aim of this work is to demonstrate some algebraic description and representations of generalized boolean algebras. The necessary information from the theory of algebraic systems semigroups, semirings, etc. is provided.

Process algebra with conditionals in the presence of epsilon

open access: yes, 2012
In a previous paper, we presented several extensions of ACP with conditional expressions, including one with a retrospection operator on conditions to allow for looking back on conditions under which preceding actions have been performed.

On essentially low, canonically well-generated Boolean algebras

open access: yesJournal of Symbolic Logic, 2002
AbstractLet B be a superatomic Boolean algebra (BA). The rank of B (rk(B)). is defined to be the Cantor Bendixon rank of the Stone space of B. If a ∈ B − {0}, then the rank of a in B (rk(a)). is defined to be the rank of the Boolean algebra . The rank of 0B is defined to be −1. An element a ∈ B − {0} is a generalized atom , if the last nonzero cardinal

A generalization of Stone’s representation theorem for Boolean algebras

open access: yesDuke Mathematical Journal, 1963
The well-known theorem of M. H. Stone [10] asserts that every Boolean algebra is isomorphic to a field of sets, that is, to a subalgebra of a complete and atomic Boolean algebra. A generalization of Boolean algebras are the Stone lattices. It is my aim to prove a representation theorem for Stone lattices: Every Stone lattice is isomorphic to a ...
