Pontryagin duality for varieties over $p$-adic fields

Algebraic Geometry 2021-12-23 v2

Abstract

We define cohomological complexes of locally compact abelian groups associated with varieties over pp-adic fields and prove a duality theorem under some assumption. Our duality takes the form of Pontryagin duality between locally compact motivic cohomology groups.

New definition of cohomology of strict normal crossing schemes (section 3), and cohomology of schemes with such reduction (section 4.3). Improved exposition in several places
