Infinitesimal characters in arithmetic families

G Dospinescu, V Paškūnas, B Schraen - arXiv preprint arXiv:2012.01041, 2020 - arxiv.org
We associate infinitesimal characters to (twisted) families of $ L $-parameters and $ C $-
parameters of $ p $-adic reductive groups. We use the construction to study the action of the …

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 …

-invariants, partially de Rham families, and local-global compatibility

Y Ding - Annales de l'Institut Fourier, 2017 - numdam.org
Let F be a totally real number field, B a quaternion algebra of center F such that there exists
only one real place of F where B is split. One can associate to B a system of quaternion …

On some consequences of a theorem of J. Ludwig

V Paškūnas - Journal of the Institute of Mathematics of Jussieu, 2022 - cambridge.org
We prove some qualitative results about the p-adic Jacquet–Langlands correspondence
defined by Scholze, in the residually reducible case, using a vanishing theorem proved by …

Big Heegner points, generalized Heegner classes and -adic -functions in the quaternionic setting

M Longo, P Magrone, ER Walchek - arXiv preprint arXiv:2401.03439, 2024 - arxiv.org
The goal of this paper is to study the $ p $-adic variation of Heegner points and generalized
Heegner classes for ordinary families of quaternionic modular forms. We compare classical …

Monodromy for some rank two Galois representations over CM fields

PB Allen, J Newton - Documenta Mathematica, 2020 - content.ems.press
We investigate local-global compatibility for cuspidal automorphic representations π for GL2
over CM fields that are regular algebraic of weight 0. We prove that for a Dirichlet density …

L-invariants and local-global compatibility for the group GL2/F

Y Ding - Forum Math. Sigma, 2016 - cambridge.org
Let F be a totally real number field,℘ a place of F above p. Let ρ be a 2-dimensional p-adic
representation of Gal (F/F) which appears in the étale cohomology of quaternion Shimura …

A p-adic Labesse–Langlands transfer

J Ludwig - manuscripta mathematica, 2017 - Springer
We prove ap-adic Labesse–Langlands transfer from the group of units in a definite
quaternion algebra to its subgroup of norm one elements. More precisely, given an …

The Jacquet–Langlands correspondence for overconvergent Hilbert modular forms

C Birkbeck - International Journal of Number Theory, 2019 - World Scientific
We use results by Chenevier to interpolate the classical Jacquet–Langlands
correspondence for Hilbert modular forms, which gives us an extension of Chenevier's …
