Equivariant Burnside groups and toric varieties

Rendiconti del Circolo Matematico di Palermo Series 2, 2021
We study G-equivariant birational geometry of toric varieties, where G is a finite group.

The Zariski–Lipman conjecture for toric varieties

Journal of Algebra, 2022
We give a short proof of the Zariski-Lipman conjecture for toric varieties: any complex toric variety with locally free tangent sheaf is smooth.Comment: Minor revisions.

Toric Varieties of Schröder Type

Proceedings of the Steklov Institute of Mathematics, 2022
A dissection of a polygon is obtained by drawing diagonals such that no two diagonals intersect in their interiors. In this paper, we define a toric variety of Schröder type as a smooth toric variety associated with a polygon dissection. Toric varieties of Schröder type are Fano generalized Bott manifolds, and they are isomorphic if and only if the ...

On stability of tangent bundle of toric varieties

Proceedings - Mathematical Sciences, 2018
Let X be a nonsingular complex projective toric variety. We address the question of semi-stability as well as stability for the tangent bundle T X . In particular, a complete answer is given when X is a Fano toric variety of dimension four with Picard ...

TANNAKIAN CLASSIFICATION OF EQUIVARIANT PRINCIPAL BUNDLES ON TORIC VARIETIES

Transformation groups, 2018

Twisted polytope sheaves and coherent–constructible correspondence for toric varieties

Selecta Mathematica, 2017
Given a smooth projective toric variety $$X_\Sigma $$XΣ of complex dimension n, Fang–Liu–Treumann–Zaslow (Invent Math 186(1):79–114, 2011) showed that there is a quasi-embedding of the differential graded (dg) derived category of coherent sheaves $$Coh ...

Characterizations of toric varieties via polarized endomorphisms

Mathematische Zeitschrift, 2017
Let X be a normal projective variety and $$f:X\rightarrow X$$f:X→X a non-isomorphic polarized endomorphism. We give two characterizations for X to be a toric variety. First we show that if X is $$\mathbb {Q}$$Q-factorial and G-almost homogeneous for some

Toric Varieties and Toric Resolutions

2000
This paper is an introduction to toric varieties and toric resolutions. We begin with basic definitions and examples, and then cover standard topics in toric geometry, including fans, support functions, and ampleness criteria. The paper also explores alternate constructions of toric varieties and nonnormal toric varieties. Then we turn our attention to
