Titre | Arithmetic matroids and Tutte polynomial |
Résumé | I will discuss the notion of arithmetic matroid, whose main example is given by a finite list of elements in a finitely generated abelian group. Guided by the geometry of toric arrangements, I will present a combinatorial intepretation of the associated arithmetic Tutte polynomial, which generalizes Crapo's formula for the classical Tutte polynomial. |
