Hopf Algebra of Sashes [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2014
A general lattice theoretic construction of Reading constructs Hopf subalgebras of the Malvenuto-Reutenauer Hopf algebra (MR) of permutations. The products and coproducts of these Hopf subalgebras are defined extrinsically in terms of the embedding in MR.

Problems in Algebraic Combinatorics

open access: yesThe Electronic Journal of Combinatorics, 1995
This is a list of open problems, mainly in graph theory and all with an algebraic flavour. Except for 6.1, 7.1 and 12.2 they are either folklore, or are stolen from other people.

3-Homogeneous Groups and Block-Transitive 7–(v, k, 3) Designs

open access: yesMathematical and Computational Applications, 2017
The classification of a block-transitive designs is an important subject on algebraic combinatorics. With the aid of MATLAB software, using the classification theorem of 3-homogeneous permutation groups, we look at the classification problem of block ...

COMBINATORICS AND N-KOSZUL ALGEBRAS [PDF]

open access: yesInternational Journal of Geometric Methods in Modern Physics, 2008
The numerical Hilbert series combinatorics for quadratic Koszul algebras was extended to N-Koszul algebras by Dubois-Violette and Popov [9]. In this paper, we give a striking application of this extension when the relations of the algebra are all the antisymmetric tensors of degree N over given variables.

Geometric Representations of Interacting Maps

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2010
Tropical geometry is a kind of dynamical scale transform which connects automata with real rational dynamics. Real rational dynamics are deeply studied from global analytic viewpoints.

Extending the parking space [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2013
The action of the symmetric group $S_n$ on the set $\mathrm{Park}_n$ of parking functions of size $n$ has received a great deal of attention in algebraic combinatorics.
