A note on some p-adic analytic Hecke actions

We show that the action of Hecke operators away from p on the space of ( p -adic) overconvergent modular forms is ( p -adically) locally analytic in a certain sense. As a corollary, the action of the Hecke algebra can be extended naturally to an action of rigid functions on its generic fiber. This directly determines the Hodge–Tate–Sen weights of Galois representation associated to an overconvergent eigenform and confirms a conjecture of Gouvêa.
