Face module for realizable Z-matroids
arXiv:1705.05816
Abstract
In this work, we define the face module for a realizable matroid over Z. Its Hilbert series is, indeed, the expected specialization of the Grothendieck - Tutte polynomial defined by Fink and Moci. This work will appear in 'Contributions to Discrete Mathematics'
