Abstract

We discuss questions concerning local-global principles for torsors under reductive groups over function fields of p-adic curves. An interesting case is when the group is defined over the p-adic integers. This leads to more general questions on torsors under reductive groups over smooth curves over henselian local domains. We shall discuss some recent progress in this study.
