Distinguishing elliptic curves modulo $p$ and identifying images of product representations

Jessica Bennett, Jeffrey Hatley, Sasha Kononova +3

Given two elliptic curves defined over $Q$ and a rational prime $p$ , we study the product of their residual Galois representations. Using Goursat's lemma, we explicitly en…

Recovering Kodaira types from $ℓ$ -torsion on elliptic curves

Naina Praveen

The classical Néron-Ogg-Shafarevich criterion characterises good reduction of an elliptic curve $E$ over a $p$ -adic field via the action of inertia on the $ℓ$ -adic Tate module.…

Restricted invertibility of continuous matrix functions

Adrian Fan, Jack Montemurro, Pavlos Motakis +4

Motivated by an influential result of Bourgain and Tzafriri, we consider continuous matrix functions $A : R \to M_{n \times n}$ and lower $ℓ_{2}$ -norm bounds associated with…
