Abstract

Let FF be a totally real number field, \wp a place of FF above pp. Let ρ\rho be a 22-dimensional pp-adic representation of Gal(Fˉ/F)\mathrm{Gal}(\bar{F}/F) which appears in the \'etale cohomology of quaternion Shimura curves (thus ρ\rho is associated to Hilbert eigenforms). When the restriction ρ:=ρD\rho_{\wp}:=\rho|_{D_{\wp}} at the decomposition group of \wp is semi-stable non-crystalline, one can associate to ρ\rho_{\wp} the so-called Fontaine-Mazur L\mathcal{L}-invariants, which are however invisible in the classical local Langlands correspondence. In this paper, we prove one can find these L\mathcal{L}-invariants in the completed cohomology group of quaternion Shimura curves, which generalizes some of Breuil's results in GL2/Q\mathrm{GL}_2/\mathbb{Q}-case.
