Higher mod $p$ Satake transforms: explicit formulas and images for $GL_{2}$

Hargun Bhatia, Yashi Jain, Casey Perdue +1

Heyer's left adjoint to derived parabolic induction gives rise to higher mod $p$ Satake transforms \[ \mathcal S_V^i: \mathcal H_G(V) \longrightarrow \mathcal H_M\bigl(H^i(K_U,V)\b…

Infinitely many elliptic curves over $Q (i)$ of exact ranks 4 and 6 with $j$ -invariant 1728

Ben Savoie

For each $r \in {4, 6}$ , we construct an explicit one-parameter family of elliptic curves over $Q (i)$ containing infinitely many pairwise nonisomorphic curves genuinely def…

Infinitely many elliptic curves over $Q (i)$ with rank 2 and $j$ -invariant 1728

Ben Savoie

We prove that there exist infinitely many elliptic curves over $Q (i)$ with $j$ -invariant $1728$ and rank exactly $2$ which are not obtained by base change from $\mathbb{Q}…

A graph-theoretic approach to computing Selmer groups of elliptic curves $y^{2} = x^{3} + b x$ over $Q (i)$

Anthony Kling, Ben Savoie

We develop a graph-theoretic algorithm to compute the $φ$ -Selmer group of the elliptic curve $E_{b} : y^{2} = x^{3} + b x$ over $Q (i)$ , where $b \in Z [i]$ and $φ$ is a de…

Non-generic components of the Emerton-Gee stack for $GL_{2}$

Kalyani Kansal, Ben Savoie

Let $K$ be a finite unramified extension of $Q_{p}$ with $p > 3$ . We study the extremely non--generic irreducible components in the reduced part of the Emerton--Gee stack fo…

Smoothness of components of the Emerton-Gee stack for $GL_{2}$

Anthony Guzman, Kalyani Kansal, Iason Kountouridis +2

Let $K$ be a finite unramified extension of $Q_{p}$ , where $p > 2$ . [CEGS22b] and [EG23] construct a moduli stack of two dimensional mod $p$ representations of the absolute Ga…
