Abstract

We complete the picture of local and global arithmetic duality theorems for short complexes of finite Galois modules and tori over $p$‑adic function fields. In view of the duality theorems, we deduce a 12‑term Poitou–Tate exact sequence which relates global Galois cohomology groups to restricted topological products of local Galois cohomology groups.
