Trianguline representations are a big class of $p$-adic representations that contains all nice enough (cristalline) ones but allow a continuous variation of weights. Global consideration suggests that the $GL_2(\mathbb{Q}_p)$ representation arising from a trianguline representation should have nonzero eigenspace under Emerton's Jacquet functor. We prove this result using purely local method as well as a generalization to $p$-adic representation of $G_F$ for $F$ unramified over $\mathbb{Q}_p$.



The talk will be on zoom, but pizza still available at 11:50am.
