The Fontaine–Mazur modularity conjecture over totally real fields

Let KK be a totally real field and let p3p\geq3 be prime. A continuous representation

ρ:GKGL2(Qp)\rho:G_K\longrightarrow\operatorname{GL}_2(\overline{\mathbb{Q}}_p)

is geometric if it satisfies the geometricity conditions of Fontaine and Mazur. The Fontaine–Mazur modularity conjecture. If ρ\rho is a geometric irreducible continuous Galois representation, then ρ\rho is modular, meaning that it arises from a Hilbert modular form over KK. This is a broad modularity prediction underlying the modular method. The source cites it as a conjecture and gives no resolution in the stated generality.
