Abstract

Let LL be a finite extension of Qp\mathbf{Q}_p. Let ρL\rho_L be a potentially semi-stable non-crystalline pp-adic Galois representation such that the associated FF-semisimple Weil-Deligne representation is absolutely indecomposable. In this paper, we study Fontaine-Mazur parabolic simple L\mathscr{L}-invariants of ρL\rho_L, which was previously only known in the trianguline case. Based on the previous work on Breuil's parabolic simple L\mathscr{L}-invariants, we attach to ρL\rho_L a locally Qp\mathbf{Q}_p-analytic representation Π(ρL)\Pi(\rho_L) of GLn(L)\mathrm{GL}_{n}(L), which carries the information of parabolic simple L\mathscr{L}-invariants of ρL\rho_L. When ρL\rho_L comes from a patched automorphic representation of G(AF+)\mathbf{G}(\mathbb{A}_{F^+}) (for a define unitary group G\mathbf{G} over a totally real field F+F^+ which is compact at infinite places and GLn\mathrm{GL}_n at pp-adic places), we prove under mild hypothesis that Π(ρL)\Pi(\rho_L) is a subrepresentation of the associated Hecke-isotypic subspace of the Banach spaces of (patched) pp-adic automophic forms on G(AF+)\mathbf{G}(\mathbb{A}_{F^+}), this is equivalent to say that the Breuil's parabolic simple L\mathscr{L}-invariants are equal to Fontaine-Mazur parabolic simple L\mathscr{L}-invariants.
