Independence of hyperlogarithms over function fields via algebraic combinatorics
We obtain a necessary and sufficient condition for the linear independence of solutions of differential equations for hyperlogarithms. The key fact is that the multiplier (i.e.

Physics, Combinatorics and Hopf Algebras
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

Combinatorics and the Schur algebra
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.

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

Combinatoric of syzygies for semigroup algebras
We describe how the graded minimal resolution of certain semigroup algebras is related to the combinatorics of some simplicial complexes. More precisely, we make explicit the isomorphism between the Tor groups of the resolution and the Koszul homology. We obtain characterizations of the Cohen-Macaulay and Gorenstein conditions.

Relative rank and regularization
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).
