Smooth quotients of complex tori by finite groups

نویسندگان

چکیده

Let $A$ be a complex torus and $G$ finite group acting on without translations such that $A/G$ is smooth. Consider the subgroup $F\leq G$ generated by elements have at least one fixed point. We prove there exists point $x\in A$ whole $F$ quotient fibration of products projective spaces over an \'etale (the being Galois with $G/F$). In particular, when $G=F$, we may assume fixes origin. This related to previous work authors, where case actions abelian varieties fixing origin was treated. Here, generalize these results tori use them reduce problem classifying smooth quotients quotients. An ingredient proof our fixed-point theorem result proving in every irreducible reflection element which not contained any proper Coxeter this property for well-generated groups. proved Stephen Griffeth appendix.

Quotients of adic spaces by finite groups

We prove that if X is an analytic adic space with an action of a finite group G, a categorical adic space quotient X/G exists under a mild hypothesis, in analogy with a classical result for schemes. We also show that if X is perfectoid, then X/G is perfectoid in many cases.

Torus quotients as global quotients by finite groups

This article is motivated by the following local-to-global question: is every variety with tame quotient singularities globally the quotient of a smooth variety by a finite group? We show that this question has a positive answer for all quasi-projective varieties which are expressible as a quotient of a smooth variety by a split torus (e.g. simplicial toric varieties). Although simplicial toric...

Determining Fuchsian groups by their finite quotients

Let C(Γ) be the set of isomorphism classes of the finite groups that are quotients (homomorphic images) of Γ. We investigate the extent to which C(Γ) determines Γ when Γ is a group of geometric interest. If Γ1 is a lattice in PSL(2,R) and Γ2 is a lattice in any connected Lie group, then C(Γ1) = C(Γ2) implies that Γ1 ∼= Γ2. If F is a free group and Γ is a right-angled Artin group or a residually...

-distortion of Finite Quotients of Amenable Groups

We study the Lp-distortion of finite quotients of amenable groups. In particular, for every 2 ≤ p < ∞, we prove that the lp-distortions of the groups C2 ≀Cn and Cpn ⋉Cn are in Θ((log n) 1/p), and that the lp-distortion of C2 n ⋉A Z, where A is the matrix (

Loci in Quotients by Finite Groups , Pointwise Stabilizers andthe

Let KV ] G be the invariant ring of a nite linear group G GL(V), and let GU be the pointwise stabilizer of a subspace U V. We prove that the following numbers associated to the invariant ring decrease if one passes from KV ] G to KV ] G U : the minimal number of homogeneous generators, the maximal degree of the generators, the number of syzygies and other Betti numbers, the complete intersectio...
