Algebraic Combinatorics of Magic Squares [PDF]

open access: yes, 2004
We describe how to construct and enumerate Magic squares, Franklin squares, Magic cubes, and Magic graphs as lattice points inside polyhedral cones using techniques from Algebraic Combinatorics.

Physics, Combinatorics and Hopf Algebras

open access: yes, 2004
A number of problems in theoretical physics share a common nucleus of combinatoric nature. It is argued here that Hopf algebraic concepts and techiques can be particularly efficient in dealing with such problems. As a first example, a brief review is given of the recent work of Connes, Kreimer and collaborators on the algebraic structure of the process

From Dedekind’s Level 12 Identities to Combinatorial Structures of Colored Partitions

open access: yesAxioms
The Dedekind η-function plays an important role in number theory, particularly in the study of modular forms, q-series, and partition identities. In this paper, we investigate several level-12 η-function identities and examine their combinatorial ...

Combinatorics and the Schur algebra

open access: yesJournal of Pure and Applied Algebra, 1993
The author studies the structure of the Schur algebra \(S_ R(n,r)\) over a commutative ring \(R\). A basis of codeterminants for this algebra is given which is analogous to the one constructed by \textit{G.-C. Rota} [Théorie combinatoire des invariants classiques, Sér. Math. Pures Appl.

Relative rank and regularization

open access: yesForum of Mathematics, Sigma
We introduce a new concept of rank – relative rank associated to a filtered collection of polynomials. When the filtration is trivial, our relative rank coincides with Schmidt rank (also called strength).
