General Serre weight conjectures

T Gee, F Herzig, D Savitt - Journal of the European Mathematical Society, 2018 - ems.press
We formulate a number of related generalisations of the weight part of Serre's conjecture to
the case of GLn over an arbitrary number field, motivated by the formalism of the Breuil …

Local models for Galois deformation rings and applications

D Le, BVL Hung, B Levin, S Morra - Inventiones mathematicae, 2023 - Springer
We construct projective varieties in mixed characteristic whose singularities model, in
generic cases, those of tamely potentially crystalline Galois deformation rings for unramified …

The Ramanujan and Sato-Tate Conjectures for Bianchi modular forms

G Boxer, F Calegari, T Gee, J Newton… - arXiv preprint arXiv …, 2023 - arxiv.org
We prove the Ramanujan and Sato-Tate conjectures for Bianchi modular forms of weight at

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 …

Conjectures and results on modular representations of GL n (K) for a p-adic field K

C Breuil, F Herzig, Y Hu, S Morra, B Schraen - 2022 - hal.science
Let p be a prime number and K a finite extension of Q p. We state conjectures on the smooth
representations of GL n (K) that occur in spaces of mod p automorphic forms (for compact …

Ordinary representations of and fundamental algebraic representations

F Herzig - Compositio Mathematica, 2011 - cambridge.org
Suppose that G is a connected reductive group over a p-adic field F, that K is a hyperspecial
maximal compact subgroup of G (F), and that V is an irreducible representation of K over the …

Weight elimination in Serre-type conjectures

D Le, BV Le Hung, B Levin - 2019 - projecteuclid.org
We prove the weight elimination direction of the Serre weight conjectures as formulated by
Herzig for forms of U (n) which are compact at infinity and split at places dividing p in generic …

Smoothness and classicality on eigenvarieties

C Breuil, E Hellmann, B Schraen - Inventiones mathematicae, 2017 - Springer
Let p be a prime number and f an overconvergent p-adic automorphic form on a definite
unitary group which is split at p. Assume that f is of “classical weight” and that its Galois …
