Complete toric varieties with reductive automorphism group
We give equivalent and sufficient criteria for the automorphism group of a complete toric variety, respectively a Gorenstein toric Fano variety, to be reductive. In particular we show that the automorphism group of a Gorenstein toric Fano variety is reductive, if the barycenter of the associated reflexive polytope is zero. Furthermore a sharp bound on the dimension of the reductive automorphism...
متن کاملToric Varieties with Huge Grothendieck Group
In each dimension n ≥ 3 there are many projective simplicial toric varieties whose Grothendieck groups of vector bundles are at least as big as the ground field. In particular, the conjecture that the Grothendieck groups of locally trivial sheaves and coherent sheaves on such varieties are rationally isomorphic fails badly.
متن کاملA Codimension Theorem for Complete Toric Varieties
Let X be a complete toric variety with homogeneous coordinate ring S. In this article, we study the codimension in the critical degree of ideals of S generated by dim(X) + 1 homogeneous elements that don’t vanish simultaneously on X. Introduction In this paper, X will denote a complete toric variety of dimension n. We will work over C, so that the torus of X is (C). The dual lattices will be de...
متن کاملJumping deformations of complete toric varieties
We construct one-parameter complex analytic families whose special fibers are complete toric varieties. Under some assumptions, the general fibers of these families also become toric varieties and we can explicitly describe the corresponding fans from the data of the fans corresponding to the special fibers. Using these families, we give a deformation family for a certain toric weakened Fano 3-...
متن کاملCodimension Theorems for Complete Toric Varieties
Let X be a complete toric variety with homogeneous coordinate ring S. In this article, we compute upper and lower bounds for the codimension in the critical degree of ideals of S generated by dim(X) + 1 homogeneous polynomials that don’t vanish simultaneously on X. Introduction In this paper, X will denote a complete toric variety of dimension n. We will work over C, so that the torus of X is (...
