$\mathcal{L}$-invariants and local-global compatibility for the group $\mathrm{GL}_2/F$

Let $F$ be a totally real number field, $\wp$ a place of $F$ above $p$. Let $ρ$ be a $2$-dimensional $p$-adic representation of $\mathrm{Gal}(\bar{F}/F)$ which appears in the étale cohomology of quaternion Shimura curves (thus $ρ$ is associated to Hilbert eigenforms). When the restriction $ρ_{\wp}:=ρ|_{D_{\wp}}$ at the decomposition group of $\wp$ is semi-stable non-crystalline, one can associate to $ρ_{\wp}$ the so-called Fontaine-Mazur $\mathcal{L}$-invariants, which are however invisible in the classical local Langlands correspondence. In this paper, we prove one can find these $\mathcal{L}$-invariants in the completed cohomology group of quaternion Shimura curves, which generalizes some of Breuil's results in $\mathrm{GL}_2/\mathbb{Q}$-case.

Some results on locally analytic socle for $\mathrm{GL}_n(\mathbb{Q}_p)$

We study some closed rigid subspaces of the eigenvarieties, constructed by using the Jacquet-Emerton functor for parabolic non-Borel subgroups. As an application (and motivation), we prove some new results on Breuil's locally analytic socle conjecture for $\mathrm{GL}_n(\mathbb{Q}_p)$.

On some partially de Rham Galois representations

We study some partially de Rham representations of $\mathrm{Gal}(\bar{L}/L)$ for a finite unramified extension $L$ of $\mathbb{Q}_p$. We study some related subspaces of Galois cohomology and of cohomology of $B$-pairs. As an application, we associate a locally $\mathbb{Q}_p$-analytic representation of $\mathrm{GL}_2(L)$ to a $2$-dimensional trianguline representation of $\mathrm{Gal}(\bar{L}/L)$, by generalizing Breuil's theory in the crystalline case.
