Ambiskew Hopf algebras [PDF]

open access: yes, 2013
Necessary and sufficient conditions are obtained for an ambiskew polynomial algebra A over a Hopf k-algebra R to possess the structure of a Hopf algebra extending that of R, in which the added variables X+ and X- are skew primitive.

Combinatorial Hopf Algebras of Simplicial Complexes [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2015
We consider a Hopf algebra of simplicial complexes and provide a cancellation-free formula for its antipode. We then obtain a family of combinatorial Hopf algebras by defining a family of characters on this Hopf algebra.

The tensor algebras of Yetter-Drinfeld module

open access: yes上海师范大学学报. 自然科学版, 2014
The antipode of a Yetter-Drinfeld Hopf algebra is an anti-algebra and anti-coalgebra map is proved.It is also proved that the tensor algebra of Yetter-Drinfeld Hopf module is a Yetter-Drinfeld Hopf algebra.

On the Cohomology of Modules over Hopf Algebras [PDF]

open access: yes, 1972
Let R be a commutative ring. Define an FH-algebra H to be a Hopf algebra and a Frobenius algebra over R with a Frobenius homomorphism ψ such that ∑(h) h(1) ψ(h(2)) = ψ(h) · 1 for all h ϵ H.

Post-Lie algebras in Regularity Structures

open access: yesForum of Mathematics, Sigma, 2023
In this work, we construct the deformed Butcher-Connes-Kreimer Hopf algebra coming from the theory of Regularity Structures as the universal envelope of a post-Lie algebra.

A Class of Weak Hopf Algebras

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2010
We introduce a class of noncommutative and noncocommutative weak Hopf algebras with infinite Ext quivers and study their structure. We decompose them into a direct sum of two algebras. The coalgebra structures of these weak Hopf algebras are described by

Quantum twist-deformed D = 4 phase spaces with spin sector and Hopf algebroid structures

open access: yesPhysics Letters B, 2019
We consider the generalized (10+10)-dimensional D=4 quantum phase spaces containing translational and Lorentz spin sectors associated with the dual pair of twist-quantized Poincare Hopf algebra H and quantum Poincare Hopf group Gˆ.

The Quantum Symmetry in Nonbalanced Hopf Spin Models Determined by a Normal Coideal Subalgebra

open access: yesJournal of Mathematics, 2021
For a finite-dimensional cocommutative semisimple Hopf C∗-algebra H and a normal coideal ∗-subalgebra H1, we define the nonbalanced quantum double DH1;H as the crossed product of H with H1op^, with respect to the left coadjoint representation of the ...

Multiplier Hopf Coquasigroup: Motivation and Biduality

open access: yesMathematics, 2022
Inspired by the multiplier Hopf algebra theory introduced by A. Van Daele, this paper introduces a new algebraic structure, a multiplier Hopf coquasigroup, by constructing the integral dual of an infinite-dimensional Hopf quasigroup with faithful ...

Twisted quantum doubles

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2004
Using diagrammatic pictures of tensor contractions, we consider a Hopf algebra (Aop⊗ℛλA*)* twisted by an element ℛλ∈A*⊗Aop corresponding to a Hopf algebra morphism λ:A→A.
