In this article we show in a unified way that both classes posses the somewhat weaker property of signability. In particular, this allows us to conclude that ...
matroid polytopes and fans are partitionable, and to prove they satisfy McMullen's upper bound theorem on the number of faces. We also discuss computational ...
We express the matroid polytope PM of a matroid M as a signed Minkowski sum of simplices, and obtain a formula for the volume of PM.
