Projective Q-factorial Toric Varieties Covered by Lines
نویسندگان
چکیده
We give a structural theorem for Q-factorial toric varieties covered by lines in P N , and compute their dual defect. This yields a characterization of defective Q-factorial toric varieties in P N. The com-binatorial description of such varieties is used to characterize some finite sets of monomials with discriminant equal to one.

Notes on Toric Varieties from Mori Theoretic Viewpoint
The main purpose of this notes is to supplement the paper [Re], which treated Minimal Model Program (also called Mori’s Program) on toric varieties. We calculate lengths of negative extremal rays of toric varieties. As an application, we obtain a generalization of Fujita’s conjecture for singular toric varieties. We also prove that every toric variety has a small projective toric Q-factorializa...
متن کاملProjective Toric Varieties as Fine Moduli Spaces of Quiver Representations
This paper proves that every projective toric variety is the fine moduli space for stable representations of an appropriate bound quiver. To accomplish this, we study the quiver Q with relations R corresponding to the finite-dimensional algebra End (⊕ r i=0 Li ) where L := (OX , L1, . . . , Lr) is a list of line bundles on a projective toric variety X . The quiver Q defines a unimodular, projec...
متن کاملSurfaces with Big Anticanonical Class
Mori dream spaces were introduced by Y. Hu and S. Keel [9]; they are natural generalizations of toric varieties. We recall the definition. Let X be a Q-factorial and normal projective variety, such that Pic(X)⊗Z Q = N(X). Let D1, . . . , Dr be a collection of divisors that give a basis for Pic(X), and whose affine hull contains the pseudoeffective cone. The Cox ring of X is the multi-graded sec...
متن کاملEquivariant Completions of Toric Contraction Morphisms
We treat equivariant completions of toric contraction morphisms as an application of the toric Mori theory. For this purpose, we generalize the toric Mori theory for non-Q-factorial toric varieties. So, our theory seems to be quite different from Reid’s original combinatorial toric Mori theory. We also explain various examples of non-Q-factorial contractions, which imply that the Q-factoriality...

This paper proves that every projective toric variety is the fine moduli space for stable representations of an appropriate bound quiver. To accomplish this, we study the quiver Q with relations R corresponding to the finite-dimensional algebra End ( ⊕r i=0 Li) where L := (OX , L1, . . . , Lr) is a list of line bundles on a projective toric variety X. The quiver Q defines a smooth projective to...
