Bounds on the coefficients of tension and flow polynomials
Breuer, Felix; Dall, Aaron Matthew (2011-05)
Article
Accés restringit per política de l'editorialThe goal of this article is to obtain bounds on the coefficients of modular and integral flow and tension polynomials of graphs. To this end we use the fact that these polynomials can be realized as Ehrhart polynomials of ... -
Internally perfect matroids
Dall, Aaron Matthew (2017-06-16)
Article
Accés obertIn 1977 Stanley proved that the $h$-vector of a matroid is an $\mathcal{O}$-sequence and conjectured that it is a pure $\mathcal{O}$-sequence. In the subsequent years the validity of this conjecture has been shown for a ... -
Matroids : h-vectors, zonotopes, and Lawrence polytopes
Dall, Aaron Matthew (Universitat Politècnica de Catalunya, 2015-02-25)
Tesi
Accés obertThe main objects of study in this thesis are matroids. In particular we are interested in three particular classes matroids: regular matroids, arithmetic matroids, and internally perfect matroids. Of these families, regular ...
