Class Number Relations in Abelian Extensions of Global Fields

Saad El Boukhari, Ben ForrÃ¡s

Consider a finite abelian extension $K / k$ of global fields with Galois group $G$ . We study the rank-one component of the generalized Stickelberger module associated with $K / k$ and…

An equivariant $p$ -adic Artin conjecture

Ben ForrÃ¡s

We formulate an equivariant version of Greenberg's $p$ -adic Artin conjecture for smoothed equivariant $p$ -adic Artin $L$ -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 ForrÃ¡s, Katharina MÃ¼ller

Let $E / Q$ be an elliptic curve and let $p \geq 5$ be a prime of good supersingular reduction. We generalize results due to Meng Fai Lim proving Kida's formula and integralit…
