Skew braces and the Yang-Baxter equation
Braces were introduced by Rump to study non-degenerate involutive set-theoretic solutions of the Yang–Baxter equation. To study non-involutive solutions one needs skew braces, a non-commutative analog of braces. In this talk we discuss basic properties of skew braces and how these structures are related to the Yang-Baxter equation. We also discuss interesting connections between skew braces and...
متن کاملCholesky-like Factorizations of Skew-symmetric Matrices
As will be shown in this paper, there always exists an R such that (1.1) holds. We present a stable O(n3) algorithm that computes an R that has the form of a permuted triangular matrix. Our motivation comes from eigenvalue problems with Hamiltonian structure. A matrix H ∈ R is said to be Hamiltonian if (JH) = JH and skew-Hamiltonian if (JH) = −JH . EXAMPLE 1. The study of corner singularities i...
متن کاملInformed Consent for Braces
The influence of law on the orthodontic profession has greatly increased in the last few decades. Dental law has emerged today as a full-fedged specialty dealing with a variety of areas, like professional negligence, doctor-patient contracts, consumer protection laws, ethics, general and special health legislations and practice regulatory mechanisms. This article highlights the concept of infor...
متن کاملProphylactic Knee Braces
The efficacy of prophylactic knee bracing has been refuted with regard to reducing the incidence and/or severity of injuries to the knee joint. This is thought to be a result of the prophylactic knee brace's ineffectiveness in protecting the knee joint from valgus loads. Furthermore, discrepancies exist regarding the prophylactic knee brace's detrimental effect on functional performance. The pu...
متن کاملBraces and brace management.
General Principles of Bracing Within recent years, reemphasis upon the rehabilitation of severely disabled individuals has "spotlighted" the importance of proper lilting braces in the teaching of ambulation and daily activities. There seem to be several points of view regarding the intelligent selection of braces for lower extre mities. One group holds that patients should be braced maximally ...
