A Regular Unimodular Triangulation of the Matroid Base Polytope
Spencer BackmanGaku Liu
文献摘要
We produce the first regular unimodular triangulation of an arbitrary matroid base polytope. We then extend our triangulation to integral generalized permutahedra. Prior to this work it was unknown whether each matroid base polytope admitted a unimodular cover.
