Reduction and lifting of special metacyclic covers
نویسنده
چکیده
Special covers are metacyclic covers of the projective line, with Galois group Z/p ⋊ Z/m, which have a specific type of bad reduction to characteristic p. Such covers arise in the study of the arithmetic of Galois covers of P with three branch points. Our results provide a classification of all special covers in terms of certain lifting data in characteristic p.

Reduction of the Hurwitz Space of Metacyclic Covers
We compute the stable reduction of some Galois covers of the projective line branched at three points. These covers are constructed using Hurwitz spaces parameterizing metacyclic covers. The reduction is determined by a certain hypergeometric differential equation. This generalizes the result of Deligne and Rapoport on the reduction of the modular curve X (p).
متن کاملTwisted Group Rings of Metacyclic Groups
Given a finite metacyclic group G, a central extension F having the projective lifting property over all fields is constructed. This extension and its group rings are used to investigate the faithful irreducible projective representations of G and the fields over which they can be realized. A full description of the finite metacyclic groups having central simple twisted group rings over fields ...
متن کاملGalois covers of the open p - adic disc
Motivated by the local lifting problem for Galois covers of curves, this paper investigates Galois branched covers of the open p-adic disc. Using the field of norms functor of Fontaine and Wintenberger, we show that the special fiber of a Galois cover is completely determined by arithmetic and geometric properties of the generic fiber and its characteristic zero specializations. As applications...

متن کاملSymplectic Group Actions and Covering Spaces
For symplectic group actions which are not Hamiltonian there are two ways to define reduction. Firstly using the cylinder-valued momentum map and secondly lifting the action to any Hamiltonian cover (such as the universal cover), and then performing symplectic reduction in the usual way. We show that provided the action is free and proper, and the Hamiltonian holonomy associated to the action i...
