Intersection theory of toric 𝑏-divisors in toric varieties [PDF]

open access: yesJournal of Algebraic Geometry, 2019
We introduce toric b b -divisors on complete smooth toric varieties and a notion of integrability of such divisors. We show

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.

Hyperbola method on toric varieties [PDF]

open access: yesJournal de l'École polytechnique. Mathématiques, 2020
We develop a very general version of the hyperbola method which extends the known method by Blomer and Br\"udern for products of projective spaces to a very large class of toric varieties.

Automorphisms of Nonnormal Toric Varieties [PDF]

open access: yesMathematical Notes, 2021
In this paper we prove criteria for a nonnormal toric variety to be flexible, to be rigid and to be almost rigid. For rigid and almost rigid toric varieties we describe the automorphism group explicitly.

Toric hyperkähler varieties

open access: yesDocumenta Mathematica, 2002
Extending work of Bielawski-Dancer citeBD and Konno citeKo, we develop a theory of toric hyperkähler varieties, which involves toric geometry, matroid theory and convex polyhedra. The framework is a detailed study of semi-projective toric varieties, meaning GIT quotients of affine spaces by torus actions, and specifically, of Lawrence toric varieties ...

Rationally Elliptic Toric Varieties [PDF]

open access: yesTokyo Journal of Mathematics, 2021
We give a characterization of all complete smooth toric varieties whose rational homotopy is of elliptic type. All such toric varieties of complex dimension not more than three are explicitly described.

A proposal for (0,2) mirrors of toric varieties [PDF]

open access: yesJournal of High Energy Physics, 2017
In this paper we propose (0,2) mirrors for general Fano toric varieties with special tangent bundle deformations, corresponding to subsets of toric deformations.

The maximum likelihood degree of toric varieties [PDF]

open access: yesJournal of symbolic computation, 2017
We study the maximum likelihood (ML) degree of toric varieties, known as discrete exponential models in statistics. By introducing scaling coefficients to the monomial parameterization of the toric variety, one can change the ML degree.

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 ...
