Abstract

En 中文
This is a continuation of our previous work on the locally analytic vectors of the completed cohomology of modular curves. We construct differential operators on modular curves with infinite level at p in both holomorphic and anti-holomorphic directions. As applications, we reprove a classicality result of Emerton which says that every absolutely irreducible two dimensional Galois representation that is regular de Rham at p and appears in the completed cohomology of modular curves comes from an eigenform. Moreover, we give a geometric description of the locally analytic representations of GL2(Qp) attached to such a Galois representation in the completed cohomology.
