Formal deformation of curves with group scheme action
We study equivariant deformations of singular curves with an action of a finite flat group scheme, using a simplified version of Illusie’s equivariant cotangent complex. We apply these methods in a special case which is relevant for the study of the stable reduction of three point covers.
متن کاملWhich weakly ramified group actions admit a universal formal deformation?
We determine exactly which formal deformation functors of representations of a finite group as weakly ramified automorphisms of a power series ring over a perfect field of positive characteristic are prorepresentable: only in characteristic two, the weak action of an involution and of the Klein group have non-pro-representable mixedcharacteristic formal deformation functors, and only the first ...
متن کاملDeformation of Outer Representations of Galois Group
To a hyperbolic smooth curve defined over a number-field one naturally associates an "anabelian" representation of the absolute Galois group of the base field landing in outer automorphism group of the algebraic fundamental group. In this paper, we introduce several deformation problems for Lie-algebra versions of the above representation and show that, this way we get a richer structure than t...
متن کاملDeformation of Chains via a Local Symmetric Group Action
A symmetric group action on the maximal chains in a finite, ranked poset is local if the adjacent transpositions act in such a way that (i, i+ 1) sends each maximal chain either to itself or to one differing only at rank i. We prove that when Sn acts locally on a lattice, each orbit considered as a subposet is a product of chains. We also show that all posets with local actions induced by label...
متن کاملA q-DEFORMATION OF A TRIVIAL SYMMETRIC GROUP ACTION
Let A be the arrangement of hyperplanes consisting of the reflecting hyperplanes for the root system An−1. Let B = B(q) be the Varchenko matrix for this arrangement with all hyperplane parameters equal to q. We show that B is the matrix with rows and columns indexed by permutations with σ, τ entry equal to qi(στ −1) where i(π) is the number of inversions of π. Equivalently B is the matrix for l...
