Tropicalizing Spherical Embeddings

Algebraic Geometry 2017-12-06 v2

Abstract

Recently, a theory for the tropicalization of a spherical homogeneous space G/HG/H was developed by Tassos Vogiannou. We extend his ideas to define the tropicalization of a spherical G/HG/H-embedding. This generalizes the construction of tropicalization of toric varieties. We also extend an alternate definition of spherical tropicalization via Gr\"obner theory developed by Kiumars Kaveh and Christopher Manon and show that the two notions of extended tropicalization coincide.
