Moduli of formal torsors

Author:

Tonini Fabio,Yasuda Takehiko

Abstract

We construct the moduli stack of torsors over the formal punctured disk in characteristic p > 0 p>0 for a finite group isomorphic to the semidirect product of a p p -group and a tame cyclic group. We prove that the stack is a limit of separated Deligne-Mumford stacks with finite and universally injective transition maps.
