A characterization of strictly APF extensions

Bryden Cais, Christopher Davis, Jonathan Lubin

Let K denote a finite extension of Qp. We give necessary and sufficient conditions for an infinite totally wildly ramified extension L/K to be strictly APF in the sense of Fontaine…

The structure of the reduction of an admissible $G$ -covering $Y \to X$ at primes $p$ dividing $∣ G ∣$ is investigated. Assume $∣ G ∣$ is not divisible by $p^{2}$ and the $p$ -Sylow group…
