Reductive covers of klt varieties

  title={Reductive covers of klt varieties},
  author={Lukas Braun and Joaqu'in Moraga},
. In this article, we study G -covers of klt varieties, where G is a reductive group. First, we exhibit an example of a klt singularity admitting a P GL n p K q -cover that is not of klt type. Then, we restrict ourselves to G -quasi-torsors, a special class of G -covers that behave like G -torsors outside closed subsets of codimension two. Given a G -quasi-torsor X Ñ Y , where G is a finite extension of a torus T , we show that X is of klt type if and only if Y is of klt type. We prove a… 



Reductive quotients of klt singularities

We prove that the quotient of a klt type singularity by a reductive group is of klt type. In particular, given a klt variety X endowed with the action of a reductive group G and admitting a

Kawamata log terminal singularities of full rank

We study Kawamata log terminal singularities of full rank, i.e., $n$-dimensional klt singularities containing a large finite abelian group of rank $n$ in its regional fundamental group. The main

Gorensteinness and iteration of Cox rings for Fano type varieties

We show that finitely generated Cox rings are Gorenstein. This leads to a refined characterization of varieties of Fano type: they are exactly those projective varieties with Gorenstein canonical

On a toroidalization for klt singularities

In this article, we prove a toroidalization principle for finite actions on klt singularities. As an application, we prove that the Jordan property for the regional fundamental group of klt

Valuation spaces and multiplier ideals on singular varieties

We generalize to all normal complex algebraic varieties the valuative characterization of multiplier ideals due to Boucksom-Favre-Jonsson in the smooth case. To that end, we extend the log

Étale fundamental groups of Kawamata log terminal spaces, flat sheaves, and quotients of Abelian varieties

Given a quasi-projective variety X with only Kawamata log terminal singularities, we study the obstructions to extending finite \'etale covers from the smooth locus $X_{\mathrm{reg}}$ of $X$ to $X$

Cox rings and pseudoeffective cones of projectivized toric vector bundles

We study projectivizations of a special class of toric vector bundles that includes cotangent bundles, whose associated Klyachko filtrations are particularly simple. For these projectivized bundles,

Birational Geometry of Algebraic Varieties

Needless to say, tlie prototype of classification theory of varieties is tlie classical classification theory of algebraic surfaces by the Italian school, enriched by Zariski, Kodaira and others. Let

Completing the Classification of Representations of SLn with Complete Intersection Invariant Ring

We present a full list of all representations of the special linear group SL n over the complex numbers with complete intersection invariant ring of homological dimension greater than or equal to

The local fundamental group of a Kawamata log terminal singularity is finite

We prove a conjecture of Kollár stating that the local fundamental group of a klt singularity x is finite. In fact, we prove a stronger statement, namely that the fundamental group of the smooth
