Local Quasitriangular Hopf Algebras [PDF]

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2008
We find a new class of Hopf algebras, local quasitriangular Hopf algebras, which generalize quasitriangular Hopf algebras. Using these Hopf algebras, we obtain solutions of the Yang-Baxter equation in a systematic way. The category of modules with finite

Quasitriangular Hopf group algebras and braided monoidal categories [PDF]

open access: yesCzechoslovak Mathematical Journal, 2014
Throughout this review, \(\pi\) denotes a discrete group with neutral element \(1\), and \(k\) denotes a field. All considered vector spaces and tensor products are assumed to be over \(k\). A \(\pi\)-algebra \(H=\{H_\alpha\}_{\alpha\in\pi}\) with multiplication \(m=\{m_{\alpha,\beta}\colon H_\alpha\otimes H_\beta\to H_{\alpha\beta}\}_{\alpha,\beta\in ...

The Brauer group of some quasitriangular Hopf algebras [PDF]

open access: yesJournal of Algebra, 2003
Let \(k\) be a field and \(H\) a Hopf algebra with bijective antipode. Then we can introduce the Brauer group \(BQ(k,H)\) of Yetter-Drinfeld module algebras [see \textit{S. Caenepeel, F. Van Oystaeyen} and \textit{Y. H. Zhang}, Trans. Am. Math. Soc. 349, No. 9, 3737-3771 (1997; Zbl 0912.16015)].

A nonlinear deformed su(2) algebra with a two-color quasitriangular Hopf structure [PDF]

open access: yes, 1997
Nonlinear deformations of the enveloping algebra of su(2), involving two arbitrary functions of J0 and generalizing the Witten algebra, were introduced some time ago by Delbecq and Quesne. In the present paper, the problem of endowing some of them with a

Quasitriangular (G-cograded) multiplier Hopf algebras

open access: yesJournal of Algebra, 2005
We put the known results on the antipode of a usual quasitriangular Hopf algebra into the framework of multiplier Hopf algebras. We illustrate with examples which can not be obtained using classical Hopf Algebras. The focus of the present paper lies on the class of the so-called group cograded multiplier Hopf algebras. By doing so, we bring the results

Braided Lie algebras and bicovariant differential calculi over co-quasitriangular Hopf algebras [PDF]

open access: yes, 2001
We show that if gΓ is the quantum tangent space (or quantum Lie algebra in the sense of Woronowicz) of a bicovariant first-order differential calculus over a co-quasitriangular Hopf algebra (A,r), then a certain extension of it is a braided Lie algebra ...

A CLASS OF QUASITRIANGULAR GROUP-COGRADED MULTIPLIER HOPF ALGEBRAS [PDF]

open access: yesGlasgow Mathematical Journal, 2018
For a multiplier Hopf algebra pairing 〈A,B〉, we construct a class of group-cograded multiplier Hopf algebras D(A,B), generalizing the classical construction of finite dimensional Hopf algebras introduced by Panaite and Staic Mihai [Isr. J. Math.

Hopf modules in the braided monoidal category $_LM$

open access: yesLe Matematiche, 2011
Suppose that L is a quasitriangular weak Hopf algebra with a bijective antipode and H is a weak Hopf algebra in the braided nonoidal category LM. We prove that the fundamental theorem for right H-Hopf modules in LM.

Quasitriangular coideal subalgebras of Uq(g) in terms of generalized Satake diagrams

open access: yesBulletin of the London Mathematical Society, Volume 52, Issue 4, Page 693-715, August 2020., 2020
Abstract Let g be a finite‐dimensional semisimple complex Lie algebra and θ an involutive automorphism of g. According to Letzter, Kolb and Balagović the fixed‐point subalgebra k=gθ has a quantum counterpart B, a coideal subalgebra of the Drinfeld–Jimbo quantum group Uq(g) possessing a universal K‐matrix K.
