Abstract

We study the structure of the stacks of twisted stable maps to the classifying stack of. a finite group G-which we call the stack of twisted G-covers, or twisted G-bundles. For a suitable group G we show that the substack. corresponding to admissible G-covers is a smooth projective fine moduli space.
