The Signed Goldman-Iwahori Space and Real Tropical Linear Spaces
Kevin Kuehn, Arne Kuhrs
For a real closed field with a non-Archimedean absolute value, we introduce the signed Goldman--Iwahori space, the space of homothety classes of signed seminorms on a finite-di…
Three lectures on tropical algebra
Jeffrey Giansiracusa, Kevin Kuehn, Stefano Mereta +1
This document is a slightly expanded version of a series of talks given by J. Giansiracusa at the workshop `Geometry over semirings' at Universitat Autònoma de Barcelona in July 2…
Minuscule Coxeter Dressians
Andreas Gross, Kevin Kuehn, Dante Luber
In this extended abstract, we study special tropical prevarieties which we call Coxeter Dressians. They arise from equations capturing a generalization of valuated symmetric basis…
Graph Curve Matroids
Alheydis Geiger, Kevin Kuehn, Raluca Vlad
We introduce a new class of matroids, called graph curve matroids. A graph curve matroid is associated to a graph and defined on the vertices of the graph as a ground set. We prove…
