Theorem 5.4: bijection between generic tropical oriented matroids and matching ensembles
Theorem 5.4: bijection between generic tropical oriented matroids and matching ensembles
A generic -tropical oriented matroid is a tropical oriented matroid whose associated structures are generic, and an -matching ensemble is the matching-field encoding introduced for generic tropical oriented matroids. Bijection theorem. Generic -tropical oriented matroids are in bijection with -matching ensembles. This gives an equivalent combinatorial encoding of generic tropical oriented matroids by matching ensembles, extending the correspondence used to study their linkage and tope arrangements.
