A local analogue of the ghost conjecture of Bergdall–Pollack

R Liu, NX Truong, L Xiao, B Zhao - Peking Mathematical Journal, 2024 - Springer
We formulate a local analogue of the ghost conjecture of Bergdall and Pollack, which
essentially relies purely on the representation theory of GL 2 (Q p). We further study the …

On Iwasawa main conjectures for elliptic curves at supersingular primes: Beyond the case ap= 0

FI Sprung - Advances in Mathematics, 2024 - Elsevier
We reduce the chromatic Iwasawa main conjecture for elliptic curves to the conjectured
existence of certain Beilinson–Flach classes in the supersingular case. This generalizes the …

New phenomena arising from L-invariants of modular forms

J Bergdall, R Pollack - arXiv preprint arXiv:2407.17411, 2024 - arxiv.org
This article explains how to practically compute L-invariants of p-new eigenforms using p-
adic L-series and exceptional zero phenomena. As proof of the utility, we compiled a data …

Lattices in rigid analytic representations

A Conti, E Torti - arXiv preprint arXiv:2403.20232, 2024 - arxiv.org
For a profinite group $ G $ and a rigid analytic space $ X $, we study when an $\mathcal
O_X (X) $-linear representation $ V $ of $ G $ admits a lattice, ie an $\mathcal O_ {\mathcal …

Determination of certain mod Galois representations using local constancy

A Ganguli, S Kumar - arXiv preprint arXiv:2406.15600, 2024 - arxiv.org
Let $ p\geq 5$ be a prime. Let $ k= b+ c (p-1) $ be an integer in $[2p+ 2, p^ 2-p+ 3] $, where
$ b\in [2, p] $ and $ c\in [2, p-1] $. We prove local constancy in the weight space of the mod …

M Deo - arXiv preprint arXiv:2401.15881, 2024 - arxiv.org
Let $ p\geq 3$ be a prime number and $ K $ be a quadratic imaginary field in which $ p $
splits as $\mathfrak {p}\overline {\mathfrak {p}} $. Let $\mathcal {F} $ be a cuspidal Bianchi …

AW Guzman - 2024 - search.proquest.com
We determine semisimple reductions of irreducible, 2-dimensional crystalline
representations of the absolute Galois group Gal (Q p/Q pf). To this end, we provide explicit …
