Pentagon Relations in Direct Sums and Grassmann Algebras [PDF]

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2013
We construct vast families of orthogonal operators obeying pentagon relation in a direct sum of three n-dimensional vector spaces. As a consequence, we obtain pentagon relations in Grassmann algebras, making a far reaching generalization of exotic ...

Direct sums of J-rings and radical rings [PDF]

open access: goldInternational Journal of Mathematics and Mathematical Sciences, 1995
Let R be a ring, J(R) the Jacobson radical of R and P the set of potent elements of R. We prove that if R satisfies (∗) given x, y in R there exist integers m=m(x,y)>1 and n=n(x,y)>1 such that xmy=xyn and if each x∈R is the sum of a potent element and a ...

Systematics of U-spin sum rules for systems with direct sums [PDF]

open access: diamondJournal of High Energy Physics
A rich mathematical structure underlying flavor sum rules has been discovered recently. In this work, we extend these findings to systems with a direct sum of representations. We prove several results for the general case.

Preventing outbreaks in burn units: the role of hygiene compliance and early warning systems [PDF]

open access: yesAntimicrobial Resistance and Infection Control
Background and objectives To analyse observations of staff’s hand hygiene, usage of gloves and plastic aprons, and dress code compliance at the Burn Centre, Uppsala University Hospital in Sweden, and to evaluate the association between hygiene non ...

New Direct Sum Tests [PDF]

open access: green
A function $f:[n]^{d} \to \mathbb{F}_2$ is a \defn{direct sum} if there are functions $L_i:[n]\to \mathbb{F}_2$ such that ${f(x) = \sum_{i}L_i(x_i)}$. In this work we give multiple results related to the property testing of direct sums. Our first result concerns a test proposed by Dinur and Golubev in 2019. We call their test the Diamond test and show

Intuitionistic fuzzy G-modules with respect to norms (T and S) [PDF]

open access: yesNotes on IFS, 2023
In this paper, we introduced intuitionistic fuzzy G-modules on M under norms (t-norm T and s-conorm S) and some related results like intersection, sum and direct sum of them has also been discussed.

Order Ideals on Lexicographic Direct Sum of Three Totally Ordered Abelian Groups [PDF]

open access: goldCauchy: Jurnal Matematika Murni dan Aplikasi
Order ideals play an important role in the study of abstract algebra, especially in the study of ordered groups. In this paper, we focus on the study of order ideals in lexicographic direct sums of totally ordered Abelian groups.

Partially Coherent Direct Sum Channels [PDF]

open access: yesQuantum, 2021
We introduce Partially Coherent Direct Sum (PCDS) quantum channels, as a generalization of the already known Direct Sum quantum channels. We derive necessary and sufficient conditions to identify the subset of those maps which are degradable, and provide a simplified expression for their quantum capacities.

On the joint continuity of module multiplication [PDF]

open access: yesProceedings of the Estonian Academy of Sciences, 2023
Let A be any topological algebra over R or C. We show that the property of a topological left (right or two-sided) A-module to have a jointly continuous action of A is inherited by submodules, quotient modules, completion, direct products, direct sums ...

Sums of slices in direct sums of Banach spaces; pp. 8–10 [PDF]

open access: yesProceedings of the Estonian Academy of Sciences, 2014
Motivated by recent studies on the strong diameter 2 property, we exhibit a simple reason why, in many direct sums of Banach spaces, the arithmetic mean of two slices may have diameter less than 2.
