Stacks of uniform cyclic covers of curves and their Picard groups
Flavia Poma, Mattia Talpo, Fabio Tonini
We study the stack B_{h,g,n} of uniform cyclic covers of degree n between smooth curves of genus h and g and, for h >> g, present it as an open substack of a vector bundle over the…
Virtual classes of Artin stacks
Flavia Poma
We construct virtual fundamental classes of Artin stacks over a Dedekind domain endowed with a perfect obstruction theory.
Gromov-Witten theory of tame Deligne-Mumford stacks in mixed characteristic
Flavia Poma
We define Gromov-Witten classes and invariants of smooth proper tame Deligne-Mumford stacks of finite presentation over a Dedekind domain. We prove that they are deformation invari…
Gromov-Witten theory of schemes in mixed characteristic
Flavia Poma
We define Gromov-Witten classes and invariants of smooth projective schemes of finite presentation over a Dedekind domain. We prove that they are deformation invariants and verify…
Étale cohomology of a DM curve-stack with coefficients in G_m
Flavia Poma
We compute the étale cohomology groups H^i(X,G_m) in several cases, where X is a smooth tame Deligne-Mumford stack of dimension 1 over an algebraically closed field. We have comple…
