Duality for the condensed Weil-étale realisation of $1$ -motives over $p$ -adic fields

Marco Artusa

We extend Tate duality for Galois cohomology of abelian varieties to $1$ -motives over a $p$ -adic field, improving a result of Harari and Szamuely. To do this, we replace Galois coh…

X-matrices

Emanuele Borgonovo, Marco Artusa, Elmar Plischke +1

We evidence a family $X$ of square matrices over a field $K$ , whose elements will be called X-matrices. We show that this family is shape invariant under multipl…

Duality for condensed cohomology of the Weil group of a p-adic field

Marco Artusa

We use the theory of Condensed Mathematics to build a condensed cohomology theory for the Weil group of a $p$ -adic field. The cohomology groups are proved to be locally compact abe…
