چکیده
We present a self-contained combinatorial approach to Fujita’s conjectures in the toric case. Our main new result is a generalization of Fujita’s very ampleness conjecture for toric varieties with arbitrary singularities. In an appendix, we use similar methods to give a new proof of an analogous toric generalization of Fujita’s freeness conjecture due to Fujino.

Fujita’s very ampleness conjecture for singular toric varieties
We present a self-contained combinatorial approach to Fujita’s conjectures in the toric case. Our main new result is a generalization of Fujita’s very ampleness conjecture for toric varieties with arbitrary singularities. In an appendix, we use similar methods to give a new proof of an anologous toric generalization of Fujita’s freeness conjecture due to Fujino. Given an ample divisor D and any...
متن کاملCombinatorial Method in Adjoint Linear Systems on Toric Varieties
For nonsingular varieties, the one-dimensional case is an easy fact in curve theory. The two-dimensional case follows from the work of Reider [16]. In higherdimensional cases, (I) is known for n = 3 [3] and n = 4 [8], and by [1] we know that KX + 1 2 (n2 +n+ 2)D is generated by global sections for all n. Less is known about (II) with one exception: if D is already very ample, then (I) and (II) ...
متن کاملNotes 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 کاملS ep 1 99 9 Topological Mirror Symmetry
The Strominger-Yau-Zaslow conjecture proposes that mirror symmetry can be explained by the existence, in a mirror pair of Calabi-Yau manifolds, of dual special La-grangian T n-fibrations. (See [18,8,6,7] for further clarification of this conjecture.) Recently, Zharkov in [20] proved that non-singular Calabi-Yau hypersurfaces in toric varieties have topological T n-fibrations, and Ruan in [17] h...
متن کاملOn the Kleiman-mori Cone
The Kleiman-Mori cone plays important roles in the birational geometry. In this paper, we construct complete varieties whose Kleiman-Mori cones have interesting properties. First, we construct a simple and explicit example of complete non-projective singular varieties for which Kleiman’s ampleness criterion does not hold. More precisely, we construct a complete non-projective toric variety X an...
