A technology for reverse-engineering a combinatorial problem from a rational generating function

open access: yes, 2001
In this paper, we tackle the problem of giving, by means of a regular language, a combinatorial interpretation of a positive sequence (f(n)) defined by a linear recurrence with integer coefficients.

A Partition Bijection Related to the Rogers-Selberg Identities and Gordon\u27s Theorem [PDF]

open access: yes, 2008
We provide a bijective map from the partitions enumerated by the series side of the Rogers–Selberg mod 7 identities onto partitions associated with a special case of Basil Gordon\u27s combinatorial generalization of the Rogers–Ramanujan identities.

Application of graph combinatorics to rational identities of type A [PDF]

open access: yes, 2008
This is the complete version of the submitted fpsac paper (2009).To a word $w$, we associate the rational function $\Psi_w = \prod (x_{w_i} - x_{w_{i+1}})^{-1}$. The main object, introduced by C.

Combinatorial Identities from the Spectral Theory of Quantum Graphs

open access: yes, 2000
The purpose of this paper is to present a newly discovered link between three seemingly unrelated subjects—quantum graphs, the theory of random matrix ensembles and combinatorics.

On the combinatorics of polynomial generalizations of Rogers-Ramanujan-type identities

open access: yes, 2015
In this paper following some ideas introduced by Andrews (Combinatorics and Ramanujan's “lost” notebook, London Mathametical Society Lecture Note Series, No. 103, Cambridge University Press, London, 1985, pp.

Recent Advances in Polyhedral Combinatorics

open access: yes, 2017
Combinatorial optimization searches for an optimal object in a finite collection; typically the collection has a concise representation while the number of objects is huge.
