Fundamental polytopes of metric trees via parallel connections of matroids

open access: yes, 2019
We tackle the problem of a combinatorial classification of finite metric spaces via their fundamental polytopes, as suggested by Vershik in 2010. In this paper we consider a hyperplane arrangement associated to every split pseudometric and, for tree-like
