A Coalgebraic Approach to Dualities for Neighborhood Frames [PDF]

open access: yesLogical Methods in Computer Science, 2022
We develop a uniform coalgebraic approach to J\'onsson-Tarski and Thomason type dualities for various classes of neighborhood frames and neighborhood algebras.

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.

A Lower Bound of the Number of Rewrite Rules Obtained by Homological Methods [PDF]

open access: yesLogical Methods in Computer Science, 2022
It is well-known that some equational theories such as groups or boolean algebras can be defined by fewer equational axioms than the original axioms. However, it is not easy to determine if a given set of axioms is the smallest or not.

Tense Operators on BL-algebras and Their Applications

open access: yesBulletin of the Section of Logic, 2021
In this paper, the notions of tense operators and tense filters in BL-algebras are introduced and several characterizations of them are obtained. Also, the relation among tense BL-algebras, tense MV-algebras and tense Boolean algebras are investigated ...

The three types of normal sequential effect algebras [PDF]

open access: yesQuantum, 2020
A sequential effect algebra (SEA) is an effect algebra equipped with a $\textit{sequential product}$ operation modeled after the Lüders product $(a,b)\mapsto \sqrt{a}b\sqrt{a}$ on C$^*$-algebras.

Algebraic theory of measure algebras

open access: yesДоповiдi Нацiональної академiї наук України, 2023
A. Horn and A. Tarski initiated the abstract theory of measure algebras. Independently V. Sushchansky, B. Oliynyk and P. Cameron studied the direct limits of Hamming spaces.

Matroids on Complete Boolean Algebras

open access: yes, 1970
The approach to a theory of non-finitary matroids, as outlined by the author in [20], is here extended to the case in which the relevant closure operators are defined on arbitrary complete Boolean algebras, rather than on the power sets of sets.
