Tropical reductive groups and principal bundles on metric graphs
Andreas Gross, Arne Kuhrs, Martin Ulirsch +1
We propose an elementary tropical analogue of a reductive group that combines the datum of a Weyl group and the tropicalization of a fixed maximal torus. For the classical groups,…

Semi-homogeneous vector bundles on abelian varieties: moduli spaces and their tropicalization
Andreas Gross, Inder Kaur, Martin Ulirsch +1
Let be an abelian variety with totally degenerate reduction over a non-Archimedean field. We describe the moduli space of semihomogeneous vector bundles on from the perspec…
