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.

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.

The prime state ideal theorem in state residuated lattices [PDF]

open access: yesCategories and General Algebraic Structures with Applications, 2023
The aim of this paper is to establish the prime state ideal theorem in state residuated lattices (SRLs). We study the state ideals lattice $\mathcal{SI}(L)$ of astate residuated lattice $(L, \varphi)$ andprove that it is a complete Brouwerian lattice ...

L-Fuzzy Prime Spectrums of ADLs

open access: yesAdvances in Fuzzy Systems, 2021
The notion of an Almost Distributive Lattice (ADL) is a common abstraction of several lattice theoretic and ring theoretic generalizations of Boolean algebra and Boolean rings.

Not all 𝜎-complete Boolean algebras are quotients of complete Boolean algebras [PDF]

open access: yesProceedings of the American Mathematical Society, 1992
In Shelah’s model of no Borel lifting of the measure algebra we show that there is a σ \sigma -complete Boolean algebra of cardinality 2 ω {2^\omega } that is not a quotient of a complete Boolean algebra. By Stone duality, there is a basically disconnected space of weight

P-Fuzzy Ideals and P-Fuzzy Filters in P-Algebras

open access: yesAdvances in Fuzzy Systems, 2021
In this paper, we introduce the concept of p-fuzzy ideals and p-fuzzy filters in a p-algebra. We provide a set of equivalent conditions for a fuzzy ideal to be a p-fuzzy ideal and a p-algebra to be a Boolean algebra.

Rough Approximation Operators on a Complete Orthomodular Lattice

open access: yesAxioms, 2021
This paper studies rough approximation via join and meet on a complete orthomodular lattice. Different from Boolean algebra, the distributive law of join over meet does not hold in orthomodular lattices. Some properties of rough approximation rely on the
