Complexity of Boolean algebras [PDF]

open access: yesTheoretical Computer Science, 1980
AbstractWe show that the elementary theory of Boolean algebras is ⩽log-complete for the Berman complexity class ...

Linear maps on real C* - algebras and related structures [PDF]

open access: yes, 2010
PhDIn this thesis we obtain new results on the structures of real C*-algebras and nonsurjective isometries between them. Some of the results have been published in [1].

Algebras for parameterised monads [PDF]

open access: yes, 2009
Parameterised monads have the same relationship to adjunctions with parameters as monads do to adjunctions. In this paper, we investigate algebras for parameterised monads. We identify the Eilenberg-Moore category of algebras for parameterised monads and

AN INTRODUCTION TO BOOLEAN ALGEBRAS [PDF]

open access: yes, 2016
This thesis discusses the topic of Boolean algebras. In order to build intuitive understanding of the topic, research began with the investigation of Boolean algebras in the area of Abstract Algebra. The content of this initial research used a particular

States on basic algebras [PDF]

open access: yesMathematica Bohemica, 2017
States on commutative basic algebras were considered in the literature as generalizations of states on MV-algebras. It was a natural question if states exist also on basic algebras which are not commutative.

A Category of Ordered Algebras Equivalent to the Category of Multialgebras

open access: yesBulletin of the Section of Logic, 2023
It is well known that there is a correspondence between sets and complete, atomic Boolean algebras (\(\textit{CABA}\)s) taking a set to its power-set and, conversely, a complete, atomic Boolean algebra to its set of atomic elements.

Amalgamation Property in the subvarieties of Gautama and Almost Gautama Algebras [PDF]

open access: yesJournal of Mahani Mathematical Research
Gautama algebras were introduced in 2022, as a common generalization of regular double Stone algebras and regular Kleene Stone algebras. Even more recently, Gautama algebras were further generalized to Almost Gautama algebras (AG for short).

Depth of Boolean Algebras

open access: yesNotre Dame Journal of Formal Logic, 2011
We prove a Theorem about the relationship between the Depth of the ultraproduct of Boolean algebras, divided by an ultrafilter, and the products of the depths of each component. This answers (partly) an open problem of Monk.

Monoids with tests and the algebra of possibly non-halting programs [PDF]

open access: yes, 2015
We study the algebraic theory of computable functions, which can be viewed as arising from possibly non-halting computer programs or algorithms, acting on some state space, equipped with operations of composition, if-then-else and while-do defined in ...

On Implicative Derivations of MTL-Algebras

open access: yesAxioms, 2022
This paper introduces the implicative derivations and gives some of their characterizations on MTL-algebras. Furthermore, we provide some representation of MTL-algebras by implicative derivations and obtain some representation of Boolean algebra via the ...
