Local Cox rings for klt singularities
Lukas Braun, Universität Freiburg, Germania
On line
Abstract
In this talk, I will discuss notions of Cox rings for (klt) singularities. We investigate different local models and how the Cox rings behave when changing the model.
Finally, we investigate an iteration process for Cox rings and compare the associated covers with covers coming from the local fundamental group.
