چکیده
We consider the algebra isomorphism found by Frenkel and Ding between the RLL and the Drinfeld realizations of Uq(ĝl(2)). After we note that this is not a Hopf algebra isomorphism, we prove that there is a unique Hopf algebra structure for the Drinfeld realization so that this isomorphism becomes a Hopf algebra isomorphism. Though more complicated, this Hopf algebra structure is also closed, just as the one found previously by Drinfeld.

با آنکه مشکل ارتباطی، عمده‌ترین نقص ناشی از کم‌شنوایی است، ممکن است مشکلات جسمی دیگری نیز با کم‌شنوایی همراه باشد. هدف این پژوهش، بررسی عملکرد اندام فوقانی در افراد کم‌شنوا با همسالان شنوای دختر و پسر با استفاده از YBT-UQ بود. نمونۀ آماری تحقیق حاضر 80 دانش‌آموز شامل40 دختر و پسر کم‌شنوای شدید تا عمیق مادرزاد (سن 77/2±10/18 و 56/2±95/17 سال) و 40 دختر و پسر شنوا (سن 60/0±55/17 و 56/0±60/17 سال)...
متن کاملMitochondrial respiration without ubiquinone biosynthesis.
Ubiquinone (UQ), a.k.a. coenzyme Q, is a redox-active lipid that participates in several cellular processes, in particular mitochondrial electron transport. Primary UQ deficiency is a rare but severely debilitating condition. Mclk1 (a.k.a. Coq7) encodes a conserved mitochondrial enzyme that is necessary for UQ biosynthesis. We engineered conditional Mclk1 knockout models to study pathogenic eff...
متن کاملIrreducible modules for the quantum affine algebra Uq( ̂ sl2) and its Borel subalgebra Uq( ̂ sl2) ≥0
Let Uq(ŝl2) ≥0 denote the Borel subalgebra of the quantum affine algebra Uq(ŝl2). We show that the following hold for any choice of scalars ε0, ε1 from the set {1,−1}. (i) Let V be a finite-dimensional irreducible Uq(ŝl2) -module of type (ε0, ε1). Then the action of Uq(ŝl2) ≥0 on V extends uniquely to an action of Uq(ŝl2) on V . The resulting Uq(ŝl2)-module structure on V is irreducible and of ...

The minimal irreducible representations of Uq[gl(m|n)], i.e. those irreducible representations that are also irreducible under Uq[osp(m|n)] are investigated and shown to be affinizable to give irreducible representations of the twisted quantum affine superalgebra Uq[gl(m|n) ]. The Uq[osp(m|n)] invariant R-matrices corresponding to the tensor product of any two minimal representations are constr...
متن کاملAn Embedding of the Universal Askey - Wilson Algebra
The Askey–Wilson algebras were used to interpret the algebraic structure hidden in the Racah–Wigner coefficients of the quantum algebra Uq(sl2). In this paper, we display an injection of a universal analog △q of Askey–Wilson algebras into Uq(sl2) ⊗ Uq(sl2) ⊗ Uq(sl2) behind the application. Moreover we formulate the decomposition rules for 3-fold tensor products of irreducible Verma Uq(sl2)-modu...
متن کاملON REPRESENTATIONS OF QUANTUM GROUPS Uq(f(K,H))
An interesting class of algebras Uq(f(K, H)) were introduced and studied in [10] as further generalizations of another class of algebras Uq(f(K)) introduced in [11] (which are similar to Uq(sl2)). This new class of algebras include the Drinfeld double of the Borel subalgebra Uq(sl2) of the quantized enveloping algebra Uq(sl2) (or equivalently the two parameter quantum groups Ur,s(sl2) as studie...
