Aspects of the category SKB of skew braces [PDF]

Communications in Algebra, 2022
We examine the pointed protomodular category SKB of left skew braces. We study the notion of commutator of ideals in a left skew brace. Notice that in the literature, “product” of ideals of skew braces is often considered. We show that the so-called (Huq

Rota—Baxter groups, skew left braces, and the Yang—Baxter equation [PDF]

Journal of Algebra, 2021
Braces were introduced by W. Rump in 2006 as an algebraic system related to the quantum Yang—Baxter equation. In 2017, L. Guarnieri and L. Vendramin defined for the same purposes a more general notion of a skew left brace. In 2021, L. Guo, H.

Skew braces from Rota–Baxter operators: a cohomological characterisation and some examples [PDF]

Annali di Matematica Pura ed Applicata, 2022
Rota–Baxter operators for groups were recently introduced by Guo, Lang, and Sheng. Bardakov and Gubarev showed that with each Rota–Baxter operator, one can associate a skew brace.

Personalized 3D-printed forearm braces as an alternative for a traditional plaster cast or splint; A systematic review.

Injury, 2022
Forearm fractures such as distal radius fractures are traditionally treated with a plaster or synthetic cast. Patients commonly report inconvenience of the cast, skin problems, and occasionally radial sensory nerve numbness. A known issue with casting is

Novel non‐involutive solutions of the Yang–Baxter equation from (skew) braces [PDF]

Journal of the London Mathematical Society, 2022
We produce novel non‐involutive solutions of the Yang–Baxter equation coming from (skew) braces. These solutions are generalisations of the known ones coming from braces and skew braces, and surprisingly in the case of braces, they are not necessarily ...

Seismic performance of an existing RC structure retrofitted with buckling restrained braces

, 2021
The use of buckling restrained braces (BRBs) represents one of the best solutions for retrofitting or upgrading the numerous existing reinforced concrete framed buildings in areas with a high seismic hazard.

The classification of scoliosis braces developed by SOSORT with SRS, ISPO, and POSNA and approved by ESPRM

European spine journal, 2022
Studies have shown that bracing is an effective treatment for patients with idiopathic scoliosis. According to the current classification, almost all braces fall in the thoracolumbosacral orthosis (TLSO) category.

Central Nilpotency of Skew Braces [PDF]

Journal of Algebra and its Applications, 2021
Skew braces are algebraic structures related to the solutions of the set-theoretic quantum YangBaxter equation. We develop the central nilpotency theory for such algebraic structures in the sense of Freese-McKenzie [9] and we compare the universal ...
