How to Draw Tropical Planes

Combinatorics 2014-12-23 v4 Algebraic Geometry

Abstract

The tropical Grassmannian parameterizes tropicalizations of linear spaces, while the Dressian parameterizes all planes in \TPn1\TP^{n-1}. We study these parameter spaces and we compute them explicitly for n7n \leq 7. Planes are identified with matroid subdivisions and with arrangements of trees. These representations are used to draw pictures.
