Algebraic and combinatorial structures on Baxter permutations [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2011
We give a new construction of a Hopf subalgebra of the Hopf algebra of Free quasi-symmetric functions whose bases are indexed by objects belonging to the Baxter combinatorial family (\emphi.e.

Amplitudes, Hopf algebras and the colour-kinematics duality

open access: yesJournal of High Energy Physics, 2022
It was recently proposed that the kinematic algebra featuring in the colour-kinematics duality for scattering amplitudes in heavy-mass effective field theory (HEFT) and Yang-Mills theory is a quasi-shuffle Hopf algebra.

Interacting Hopf algebras [PDF]

open access: yesJournal of Pure and Applied Algebra, 2017
We introduce the theory IH of interacting Hopf algebras, parametrised over a principal ideal domain R. The axioms of IH are derived using Lack's approach to composing PROPs: they feature two Hopf algebra and two Frobenius algebra structures on four different monoid-comonoid pairs.

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.

Monomial Hopf algebras

open access: yesJournal of Algebra, 2004
Let $K$ be a field of characteristic 0 containing all roots of unity. We classify all the Hopf structures on monomial $K$-coalgebras, or, in dual version, on monomial $K$-algebras.

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
