Seminar der Forschergruppe 'Symmetrie, Geometrie und Arithmetik'

Given a definite unitary group $G$ that is isomorphic to $\mathrm{GL_n}$ at the $p$-adic places, the $p$-adic Galois representations attached to $p$-adic overconvergent automorphic forms for $G$ are known to be trianguline at $p$ in the sense of ($\varphi$, $\Gamma$)-modules or $B$-pairs. It is conjectured that this condition characterizes all such representations. We show that a $p$-adic Galois representation is trianguline at $p$ if and only it is trianguline after composition with a Schur functor. We give an application of this result to the study of the Galois image at points of the eigenvariety for $G$.
