Local-global compatibility for l = p , I

Thomas Barnet-Lamb, Toby Gee, David Geraghty, Richard Taylor (2012)

Annales de la faculté des sciences de Toulouse Mathématiques

We prove the compatibility of the local and global Langlands correspondences at places dividing l for the l -adic Galois representations associated to regular algebraic conjugate self-dual cuspidal automorphic representations of GL n over an imaginary CM field, under the assumption that the automorphic representations have Iwahori-fixed vectors at places dividing l and have Shin-regular weight.

Locally analytic vectors of unitary principal series of  GL 2 ( p )

Ruochuan Liu, Bingyong Xie, Yuancao Zhang (2012)

Annales scientifiques de l'École Normale Supérieure

The p -adic local Langlands correspondence for  GL 2 ( p ) attaches to any 2 -dimensional irreducible p -adic representation V of  G p an admissible unitary representation Π ( V ) of  GL 2 ( p ) . The unitary principal series of  GL 2 ( p ) are those Π ( V ) corresponding to trianguline representations. In this article, for  p > 2 , using the machinery of Colmez, we determine the space of locally analytic vectors Π ( V ) an for all non-exceptional unitary principal series Π ( V ) of  GL 2 ( p ) by proving a conjecture of Emerton.

New models for the action of Hecke operators in spaces of Maass wave forms

Ian Kiming (2007)

Annales de l’institut Fourier

Utilizing the theory of the Poisson transform, we develop some new concrete models for the Hecke theory in a space M λ ( N ) of Maass forms with eigenvalue 1 / 4 - λ 2 on a congruence subgroup Γ 1 ( N ) . We introduce the field F λ = ( λ , n , n λ / 2 n ) so that F λ consists entirely of algebraic numbers if λ = 0 .The main result of the paper is the following. For a packet Φ = ( ν p p N ) of Hecke eigenvalues occurring in M λ ( N ) we then have that either every ν p is algebraic over F λ , or else Φ will – for some m – occur in the first cohomology of a certain space W λ , m which is a...
