چکیده

Let Z → X be a nite branched Galois cover of normal projective geometrically integral varieties of dimension d ≥ 2 over a perfect eld k. For such a cover, we prove a Chebotarev-type density result describing the decomposition behaviour of geometrically integral Cartier divisors. As an application, we classify Galois covers among all nite branched covers of a given normal geometrically integral variety X over k by the decomposition behaviour of points of a xed codimension r with 0 < r < dimX.

Base Point Free Theorems —saturation, B-divisors, and Canonical Bundle Formula—

We reformulate the Kawamata-Shokurov base point free theorem by using the notion of b-divisors and saturation of linear systems, which was introduced by Shokurov. Combining the refined Kawamata-Shokurov base point free theorem with Ambro’s canonical bundle formula, we quickly reprove the main theorem of Kawamata’s paper: Pluricanonical systems on minimal algebraic varieties, without using the n...

Algebraic dynamical systems and Dirichlet’s unit theorem on arithmetic varieties

In this paper, we study obstructions to the Dirichlet property by two approaches : density of non-positive points and functionals on adelic R-divisors. Applied to the algebraic dynamical systems, these results provide examples of nef adelic arithmetic R-Cartier divisor which does not have the Dirichlet property. We hope the obstructions obtained in the article will give ways toward criteria of ...

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...

Polyhedral Divisors and Algebraic Torus Actions

We provide a complete description of normal affine varieties with effective algebraic torus action in terms of what we call proper polyhedral divisors on semiprojective varieties. Our theory extends classical cone constructions of Dolgachev, Demazure and Pinkham to the multigraded case, and it comprises the theory of affine toric varieties.
