A Serre weight conjecture for geometric Hilbert modular forms in characteristic

F Diamond, S Sasaki - Journal of the European Mathematical …, 2022 - content.ems.press
Let p be a prime and F a totally real field in which p is unramified. We consider mod p Hilbert
modular forms for F, defined as sections of automorphic line bundles on Hilbert modular …

Unramifiedness of Galois representations arising from Hilbert modular surfaces

M Emerton, D Reduzzi, L Xiao - Forum of Mathematics, Sigma, 2017 - cambridge.org
Let p be a prime number and F a totally real number field. For each prime p of F above p we
construct a Hecke operator Tp acting on (mod pm) Katz Hilbert modular classes which …

Unramifiedness of weight one Hilbert Hecke algebras

SV Deo, M Dimitrov, G Wiese - arXiv preprint arXiv:1911.11196, 2019 - arxiv.org
We prove that the Galois pseudo-representation valued in the mod $ p^ n $ cuspidal Hecke
algebra for GL (2) over a totally real number field $ F $, of parallel weight $1 $ and level …

[HTML][HTML] Compactifications of Iwahori-level Hilbert modular varieties

F Diamond - Journal of Number Theory, 2024 - Elsevier
We study minimal and toroidal compactifications of p-integral models of Hilbert modular
varieties. We review the theory in the setting of Iwahori level at primes over p, and extend it …

[PDF][PDF] Minimal weights of mod p Galois representations

H Wiersema - 2021 - kclpure.kcl.ac.uk
Serre's strong conjecture, now a theorem of Khare and Wintenberger, states that every two-
dimensional continuous, odd, irreducible mod p Galois representation ρ: GQ→ GL2 (Fp) …

Hilbert modular forms modulo p of partial weight one and unramifiedness of Galois representations

M De Maria - 2020 - orbilu.uni.lu
This thesis studies Hilbert modular forms of arbitrary weight with coefficients over a finite
field of characteristic p. In particular, we compute the action on geometric q-expansions …

Kodaira-Spencer isomorphisms and degeneracy maps on Iwahori-level Hilbert modular varieties: the saving trace

F Diamond - arXiv preprint arXiv:2111.10160, 2021 - arxiv.org
We consider integral models of Hilbert modular varieties with Iwahori level structure at
primes over p, first proving a Kodaira-Spencer isomorphism that gives a concise description …

On congruence modules related to Hilbert Eisenstein series

SC Shih - Mathematische Zeitschrift, 2020 - Springer
We generalize the work of Ohta on the congruence modules attached to elliptic Eisenstein
series to the setting of Hilbert modular forms. Our work involves three parts. In the first part …

Geometric modularity for algebraic and non-algebraic weights

H Wiersema - arXiv preprint arXiv:2205.00946, 2022 - arxiv.org
In this short paper we generalise a result of Diamond--Sasaki connecting geometric
modularity of algebraic weights to geometric modularity of non-algebraic weights and vice …
