Extensions of transversal valuated matroids
Alex M. Fink, Jorge Alberto Olarte · arXiv (Cornell University) · 2023
Following up on our previous work, we study single-element extensions of transversal valuated matroids. We show that tropical presentations of valuated matroids with a minimal set of finite entries enjoy counterparts of the properties proved by Bonin and de Mier of minimal non-valuated transversal presentations.
