Valuative and geometric characterizations of Cox sheaves

Autor: Benjamin Bechtold

Publikováno v: J. Commut. Algebra 10, no. 1 (2018), 1-43

We give an intrinsic characterization of Cox sheaves on Krull schemes in terms of their valuative algebraic properties. We also provide a geometric characterization of their graded relative spectra in terms of good quotients of graded schemes, extend

Factorially graded rings and Cox rings

Autor: Benjamin Bechtold

Publikováno v: Journal of Algebra. 369:351-359

Cox rings of normal prevarieties are factorially graded, i.e. homogeneous elements allow a unique decomposition into homogeneous factors. We study this property from an algebraic point of view and give a criterion which in a sense reduces it to facto

On terminal Fano 3-folds with 2-torus action

Autor: Benjamin Bechtold, Jürgen Hausen, Elaine Huggenberger, Michele Nicolussi

We classify the terminal Fano threefolds of Picard number one that come with an effective action of a two-torus. Our approach applies also to higher dimensions and generalizes the correspondence between toric Fano varieties and lattice polytopes: to
