Combinatorial Hopf algebras from renormalization [PDF]

open access: yes, 2009
In this paper we describe the right-sided combinatorial Hopf structure of three Hopf algebras appearing in the context of renormalization in quantum field theory: the non-commutative version of the Fa\`a di Bruno Hopf algebra, the non-commutative version

Semisimple Hopf Algebras

open access: yesJournal of Algebra, 1995
The authors study the structure of finite dimensional semisimple Hopf algebras over a field \(K\), using the trace formula, the Nichols-Zoeller theorem [\textit{W. D. Nichols} and \textit{M. B. Zoeller}, J. Pure Appl. Algebra 56, 51-57 (1989; Zbl 0659.16006)] and the authors' results in other papers.

κ-deformed BMS symmetry

open access: yesPhysics Letters B, 2019
We present the quantum κ-deformation of BMS symmetry, by generalizing the lightlike κ-Poincaré Hopf algebra. On the technical level our analysis relies on the fact that the lightlike κ-deformation of Poincaré algebra is given by a twist and the lightlike

The category of affine algebraic regular monoids

open access: yesAIMS Mathematics, 2022
The main aim of this study is to characterize affine weak $ k $-algebra $ H $ whose affine $ k $-variety $ S = M_{k}(H, k) $ admits a regular monoid structure.

Integrals in Hopf algebras over rings [PDF]

open access: yes, 2003
Integrals in Hopf algebras are an essential tool in studying finite dimensional Hopf algebras and their action on algebras. Over fields it has been shown by Sweedler that the existence of integrals in a Hopf algebra is equivalent to the Hopf algebra ...

Biperfect Hopf Algebras

open access: yesJournal of Algebra, 2000
Recall that a finite group is called perfect if it does not have non-trivial 1-dimensional representations (over the field of complex numbers C). By analogy, let us say that a finite dimensional Hopf algebra H over C is perfect if any 1-dimensional H-module is trivial. Let us say that H is biperfect if both H and H^* are perfect.

基本弱Hopf代数和弱覆盖箭图(Basic weak Hopf algebra and weak covering quiver)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2016
We introduce a finite-dimensional basic and split weak Hopf algebra H over an algebraically closed field k with strongly graded Jacobson radical r. We obtain some structures of a finite-dimensional basic and split semilattice graded weak Hopf algebra,and

Hopf Differential Graded Galois Extensions

open access: yesMathematics, 2022
We introduce the concept of Hopf dg Galois extensions. For a finite dimensional semisimple Hopf algebra H and an H-module dg algebra R, we show that D(R#H)≅D(RH) is equivalent to that R/RH is a Hopf differential graded Galois extension.

Hopf algebra structures on generalized quaternion algebras

open access: yesElectronic Research Archive
In this paper, we use elementary linear algebra methods to explore possible Hopf algebra structures within the generalized quaternion algebra. The sufficient and necessary conditions that make the generalized quaternion algebra a Hopf algebra are given ...
