Hom-L-R-smash products, Hom-diagonal crossed products and the Drinfeld double of a Hom-Hopf algebra [PDF]
We introduce the Hom-analogue of the L-R-smash product and use it to define the Hom-analogue of the diagonal crossed product. When H is a finite dimensional Hom-Hopf algebra with bijective antipode and bijective structure map, we define the Drinfeld ...

The doubles of a braided Hopf algebra [PDF]
Let A be a Hopf algebra in a braided rigid category B. In the case B admits a coend C, which is a Hopf algebra in B, we defined in 2008 the double D(A) of A, which is a quasitriangular Hopf algebra in B whose category of modules is isomorphic to the ...

Quasitriangular Hopf algebras of dimension pq^2
Let p and q be distinct odd primes and assume k is an algebraically closed field of characteristic zero. We classify all quasitriangular Hopf algebras of dimension pq^2 over k, which are not simple as Hopf algebras. Moreover, we obtained all quasitriangular structures on these Hopf algebras.

Some isomorphisms for the Brauer groups of a Hopf algebra
Using equivalences of categories we provide general isomorphisms between the Brauer groups of different Hopf algebras. One of those is used to prove that the Brauer groups BC(k, H_4, r(1)) for every dual quasitriangular structure r(t) on Sweedler's Hopf ...

Tressages des groupes de Poisson formels à dual quasitriangulaire [PDF]
In [V. G. Drinfeld, "Quantum groups", Proc. Intern. Congress of Math. (Berkeley, 1986) 1987, pp. 798-820], Drinfeld constructs a Quantum Formal Series Hopf Algebra (QFSHA) U'_h starting from a Quantum Universal Enveloping Algebra (QUEA) U_h .

Symmetry of quasitriangular structures on some Hopf algebras
Abstract Let H be a Hopf algebra. The concept of symmetry of a quasitriangu-lar structure on H is introduced and some properties of a symmetric quasitriangular structure are characterized. We apply this to study quasitriangular structures on small quantum groups and abelian extensions.

On the subgroup structure of the full Brauer group of Sweedler Hopf algebra
We introduce a three-parameter family of two-dimensional algebras representing elements in the Brauer group BQ(k,H _4) of Sweedler Hopf algebra H_4 over a field k.

Classifying bicrossed products of two Sweedler's Hopf algebras [PDF]
summary:We continue the study started recently by Agore, Bontea and Militaru in ``Classifying bicrossed products of Hopf algebras'' (2014), by describing and classifying all Hopf algebras $E$ that factorize through two Sweedler's Hopf algebras ...

Nonassociative constructions from inverse property quasigroups
PhDThe notion of a Hopf algebra has been generalized many times by weakening certain properties; we introduce Hopf quasigroups which weaken the associativity of the algebra.
