Well quasi-order in combinatorics : embeddings and homomorphisms [PDF]

open access: yes, 2015
The notion of well quasi-order (wqo) from the theory of ordered sets often arises naturally in contexts where one deals with infinite collections of structures which can somehow be compared, and it then represents a useful discriminator between ‘tame ...

Arc Spaces and Rogers-Ramanujan Identities [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2011
Arc spaces have been introduced in algebraic geometry as a tool to study singularities but they show strong connections with combinatorics as well. Exploiting these relations we obtain a new approach to the classical Rogers-Ramanujan Identities.

Toric degenerations of Grassmannians from matching fields [PDF]

open access: yes, 2019
We study the algebraic combinatorics of monomial degenerations of Plücker forms which is governed by matching fields in the sense of Sturmfels and Zelevinsky.

Cluster algebras of infinite rank [PDF]

open access: yes, 2014
Holm and Jørgensen have shown the existence of a cluster structure on a certain category D that shares many properties with finite type A cluster categories and that can be fruitfully considered as an infinite analogue of these. In this work we determine

Chromatic roots as algebraic integers [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2012
A chromatic root is a zero of the chromatic polynomial of a graph. At a Newton Institute workshop on Combinatorics and Statistical Mechanics in 2008, two conjectures were proposed on the subject of which algebraic integers can be chromatic roots, known ...

An introduction to Smarandache multi-spaces and mathematical combinatorics [PDF]

open access: yes, 2007
These Smarandache spaces are right theories for objectives by logic. However, the mathematical combinatorics is a combinatorial theory for branches in classical mathematics motivated by a combinatorial speculation.
