Subdivisions of root polytopes, generalized tropical oriented matroids, and generalized matching ensembles

Tianyu Jiang, Yuan Yao, Qingyue Yu +1

We study a generalization of tropical oriented matroids by Ardila and Develin, and show that they are in bijection with subdivisions of root polytopes, which are sub-polytopes of a…
