Abstract

Certain issues arise while considering Local Tate duality over characteristics $p>0$, when the Galois module has $p$-torsion. A solution was given by Shatz, where he considered finite flat group schemes instead of Galois modules and the dual group is Cartier dual. The duality theorem is then a topological duality of the cohomology groups. We give a more natural construction and proof of the topological aspects of the duality theorem. This is joint work with Manodeep Raha.
