Discriminants of toric varieties [PDF]

open access: yesCommunications in Algebra, 2021
We study the subvariety of singular sections, the discriminant, of a base point free linear system $|L|$ on a smooth toric variety $X$. On one hand we describe pairs $(X,L)$ for which the discriminant is of low dimension. Precisely, we collect some bounds on this dimension and classify those pairs whose dimension differs the bound less than or equal to

Fibered Toric Varieties

open access: yesMoscow Mathematical Journal, 2023
A toric variety is called fibered if it can be represented as a total space of fibre bundle over toric base and with toric fiber. Fibered toric varieties form a special case of toric variety bundles. In this note we first give an introduction to the class of fibered toric varieties.

Residues in toric varieties [PDF]

open access: yesCompositio Mathematica, 1997
We study residues on a complete toric variety $X$ , which are defined in terms of the homogeneous coordinate ring of $X$ . We first prove a global transformation law for toric residues.

Extensions of Toric Varieties [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2011
In this paper, we introduce the notion of "extension" of a toric variety and study its fundamental properties. This gives rise to infinitely many toric varieties with a special property, such as being set theoretic complete intersection or arithmetically Cohen-Macaulay (Gorenstein) and having a Cohen-Macaulay tangent cone or a local ring with non ...

Nearest points on toric varieties [PDF]

open access: yesMATHEMATICA SCANDINAVICA, 2018
We determine the Euclidean distance degree of a projective toric variety. This extends the formula of Matsui and Takeuchi for the degree of the $A$-discriminant in terms of Euler obstructions. Our primary goal is the development of reliable algorithmic tools for computing the points on a real toric variety that are closest to a given data point.

Homogeneous Toric Varieties

open access: yesJournal of Lie Theory, 2010
A description of transitive actions of a semisimple algebraic group G on toric varieties is obtained. Every toric variety admitting such an action lies between a product of punctured affine spaces and a product of projective spaces. The result is based on the Cox realization of a toric variety as a quotient space of an open subset of a vector space V ...
