Extended Affine Root Systems
There are two notions of the extended affine root systems in the literature which both are introduced axiomatically. One, extended affine root system (SAERS for short), consists only of nonisotropic roots, while the other, extended affine root system (EARS for short), contains certain isotropic roots too. We show that there is a one to one correspondence between (reduced) SEARSs and EARSs. Name...
متن کاملThe Classification of Convex Orders on Affine Root Systems
We classify all total orders having a certain convexity property on the positive root system of an arbitrary untwisted affine Lie algebra g. Such total orders are called convex orders and were used to construct Poincaré-BirkhoffWitt type bases of the upper triangular subalgebra of the quantized enveloping algebra of g which are called convex bases.
متن کاملA functional thumb metacarpal extension blocking splint.
As therapists, we frequently perform manual massage, scar massage and joint mobilizations. These types of treatments often can cause pain at the metacarpal joint of the therapist’s thumb. Other professions, as well as activities, may also produce symptoms in this joint. The authors of this article have developed a splint to help protect our thumbs. — PEGGY L. FILLION, OTR, CHT, Practice Forum E...
متن کاملImpact of Extension Splint on Upper Extremity Motor Components and Function in Chronic Stroke Patients
Objectives: Spasticity and contracture in flexor muscles of the wrist may occur after stroke, especially in which early recovery did not appear. Splints are prescribed to reduce spasticity and to prevent contracture after stroke. Although there is a few research in this field. The aim of this study was to examine the impact of the Extension splint on function, spasticity, and range of motion of...
متن کاملParametrizations of Infinite Biconvex Sets in Affine Root Systems
We investigate in detail relationships between the set B of all infinite “biconvex” sets in the positive root system ∆+ of an arbitrary untwisted affine Lie algebra g and the set W of all infinite “reduced word” of the Weyl group of g. The study is applied to the classification of “convex orders” on ∆+ (cf. [Ito]), which are indispensable to construct “convex bases” of PoincaréBirkhoff-Witt typ...
