Galois representations modulo p and cohomology of Hilbert modular varieties

M Dimitrov - Annales scientifiques de l'Ecole normale supérieure, 2005 - Elsevier
The aim of this paper is to extend some arithmetic results on elliptic modular forms to the
case of Hilbert modular forms. Among these results let us mention: We study the arithmetic …

p-adic cohomology and classicality of overconvergent Hilbert modular forms

Y Tian, L Xiao - arXiv preprint arXiv:1308.0779, 2013 - arxiv.org
Let $ F $ be a totally real field in which $ p $ is unramified. We prove that, if a cuspidal
overconvergent Hilbert cuspidal form has small slopes under $ U_p $-operators, then it is …
