Face module for realizable Z-matroids
Published 16 May 2017 in math.CO and math.AC | (1705.05816v3)
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'
