Modularity theorems for Eisenstein congruences in prime-power level

Jaclyn Lang, Katharina Müller, Bharathwaj Palvannan

Let $p, N \geq 5$ be primes such that $N \equiv 1 mod p$ . We prove modularity theorems at levels $N$ and $N^{2}$ , showing that suitable Eisenstein localizations of the weight- $2$ $…

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

Ben Forrás, Katharina Müller

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…
