%0 Journal Article %T Modularity of the Consani-Scholten quintic %A Luis Dieulefait %A Ariel Pacetti %A Matthias Schuett %J Mathematics %D 2010 %I arXiv %X We prove that the Consani-Scholten quintic, a Calabi-Yau threefold over QQ, is Hilbert modular. For this, we refine several techniques known from the context of modular forms. Most notably, we extend the Faltings-Serre-Livne method to induced four-dimensional Galois representations over QQ. We also need a Sturm bound for Hilbert modular forms; this is developed in an appendix by Jose Burgos Gil and the second author. %U http://arxiv.org/abs/1005.4523v3
