Tropicalizing Spherical Embeddings
Evan D. Nash · arXiv (Cornell University) · 2016
Recently, a theory for the tropicalization of a spherical homogeneous space $G/H$ was developed by Tassos Vogiannou. We extend his ideas to define the tropicalization of a spherical $G/H$-embedding. This generalizes the construction of tropicalization of toric varieties. We also extend an alternate definition of spherical tropicalization via Gröbner theory developed by Kiumars Kaveh and Christopher Manon and show that the two notions of extended tropicalization coincide.
