Compactifications of Iwahori-level Hilbert modular varieties

Fred Diamond

We study minimal and toroidal compactifications of -integral models of Hilbert modular varieties. We review the theory in the setting of Iwahori level at primes over , and ex…

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

Fred Diamond

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…

Geometric weight-shifting operators on Hilbert modular forms in characteristic p

Fred Diamond

We carry out a thorough study of weight-shifting operators on Hilbert modular forms in characteristic , generalizing the author's prior work with Sasaki to the case where is…

The cone of minimal weights for mod Hilbert modular forms

Fred Diamond, Payman L Kassaei

We prove that all mod Hilbert modular forms arise via multiplication by generalized partial Hasse invariants from forms whose weight falls within a certain minimal cone. This a…

A mod p Jacquet-Langlands relation and Serre filtration via the geometry of Hilbert modular varieties: Splicing and dicing

Fred Diamond, Payman Kassaei, Shu Sasaki

We consider Hilbert modular varieties in characteristic p with Iwahori level at p and construct a geometric Jacquet-Langlands relation showing that the irreducible components are i…

A Serre weight conjecture for geometric Hilbert modular forms in characteristic p

Fred Diamond, Shu Sasaki

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 modu…
