Julian Kiverstein,Michael Kirchhoff, conjecturally, determine . as a subscheme. Using ., we prove that these equations generate the ideal for 5 ≤ . ≤ 8. For . ≤ 6, we also give a cohomological proof that these polynomials realize . as a subvariety of . embedded by the complete log canonical linear system.

Mark-Oliver Casper,Giuseppe Flavio Arteserms of these generators generate the initial algebra of this Cox ring. Sturmfels and Xu provide a classification in the case of degree 4 del Pezzo surfaces by subdividing the tropical Grassmannian .. After providing the necessary background on Cox–Nagata rings and Khovanskii bases, we review the cla

We establish basic facts about the Specht polytope: the symmetric group acts transitively on its vertices and irreducibly on its ambient real vector space. A similar construction builds a matroid and polytope for a tensor product of

Simon Receveur,David Scheler,Tim Fingscheidt we compare toric degenerations arising from string polytopes and the FFLV polytope with those obtained from the tropicalization of the flag varieties. We also present a general procedure to find toric degenerations in the cases where the initial ideal arising from a cone of the tropicalization of a

As motivation, we summarize some results from toric and tropical geometry linking cellular sheaf cohomologies to cohomologies of algebraic varieties. We then give an overview of the structure of the extension . for .. Finally, we illustrate the usage of the extension with examples from
