Dissimilarity Vectors of Trees and Their Tropical Linear Spaces (Extended Abstract)

International audience We study the combinatorics of weighted trees from the point of view of tropical algebraic geometry and tropical linear spaces. The set of dissimilarity vectors of weighted trees is contained in the tropical Grassmannian, so we describe here the tropical linear space of a dissi...
