Graduated orders over completed group rings and conductor formulæ

Ben Forrás

We study graduated orders over completed group rings of -dimensional admissible -adic Lie groups, and verify the equivariant -adic Artin conjecture for such orders. Follow…

An equivariant -adic Artin conjecture

Ben Forrás

We formulate an equivariant version of Greenberg's -adic Artin conjecture for smoothed equivariant -adic Artin -functions in the context of an arbitrary one-dimensional ad…

On the cohomology of plus/minus Selmer groups of supersingular elliptic curves in weakly ramified base fields

Ben Forrás, Katharina Müller

Let be an elliptic curve and let be a prime of good supersingular reduction. We generalize results due to Meng Fai Lim proving Kida's formula and integralit…
