Perfect disjunctive normal forms in a class of algebras

open access: yesНауковий вісник Ужгородського університету. Серія: Математика і інформатика, 2017
The methods of constructing normal forms in the class of algebras are considered. Formulas of algebra describe Boolean images.

Idempotent generated algebras and Boolean powers of commutative rings [PDF]

open access: yes, 2013
A Boolean power S of a commutative ring R has the structure of a commutative R-algebra, and with respect to this structure, each element of S can be written uniquely as an R-linear combination of orthogonal idempotents so that the sum of the idempotents ...

Impact of Packaging and Recycling Systems on Material Recirculation: A Stage‐Decomposition Model

open access: yesPackaging Technology and Science, EarlyView.
A system‐level view emerges from decomposing recycling into four stages (participation, collection, sorting and process yield), diagnosing constraints and targeting interventions. Cumulative equivalent uses (CEUs) quantify long‐term retention, revealing marginal improvements at high baselines generate disproportionately larger gains than low‐baseline ...

Monotone, free, and boolean cumulants: a shuffle algebra approach

open access: yes, 2018
The theory of cumulants is revisited in the "Rota way", that is, by following a combinatorial Hopf algebra approach. Monotone, free, and boolean cumulants are considered as infinitesimal characters over a particular combinatorial Hopf algebra. The latter

Necessary and Sufficient Conditions in Trust Development Over Time: Understanding the Borrower–Lender Relationship

open access: yesBritish Journal of Management, EarlyView.
Abstract We explore configurations of sufficient and necessary conditions for the evolution and resilience of borrower trust in their lenders. Because trust is a dynamic phenomenon that needs to be understood in terms of change over time, we rely on longitudinal data collected from managers of small‐ and medium‐sized enterprises (SME) who are clients ...

Boolean Algebra of C-Algebras

open access: yesJournal of Mathematical and Fundamental Sciences, 2014
A C- algebra is the algebraic form of the 3-valued conditional logic, which was introduced by F. Guzman and C.C. Squier in 1990. In this paper, some equivalent conditions for a C- algebra to become a boolean algebra in terms of congruences are given.

The Boolean algebra of Galois algebras

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2003
Let B be a Galois algebra with Galois group G, Jg={b∈B|bx=g(x)b for all x∈B} for each g∈G, and BJg=Beg for a central idempotent eg, Ba the Boolean algebra generated by {0,eg|g∈G}, e a nonzero element in Ba, and He={g∈G|eeg=e}.

Extension by Conservation. Sikorski's Theorem [PDF]

open access: yesLogical Methods in Computer Science, 2018
Constructive meaning is given to the assertion that every finite Boolean algebra is an injective object in the category of distributive lattices. To this end, we employ Scott's notion of entailment relation, in which context we describe Sikorski's ...

Boolean algebras and Lubell functions [PDF]

open access: yes, 2013
Let $2^{[n]}$ denote the power set of $[n]:=\{1,2,..., n\}$. A collection $\B\subset 2^{[n]}$ forms a $d$-dimensional {\em Boolean algebra} if there exist pairwise disjoint sets $X_0, X_1,..., X_d \subseteq [n]$, all non-empty with perhaps the exception ...

Survey‐Based Research for Creativity and Innovation Management: Review and Recommendations

open access: yesCreativity and Innovation Management, EarlyView.
ABSTRACT Survey methodology remains a widely used data collection method in creativity and innovation management studies. However, evolving technological advancements and methodological challenges necessitate a reassessment of best practices to benefit the most from it.
