Lubin-Tate theory and overconvergent Hilbert modular forms of low weight
Abstract
Let be a finite extension of and let be the Galois group of the cyclotomic extension of . Fontaine's theory gives a classification of -adic representations of in terms of -modules. A useful aspect of this classification is Berger's dictionary which expresses invariants coming from -adic Hodge theory in terms of these -modules. In this paper, we use the theory of locally analytic vectors to generalize this dictionary to the setting where is the Galois group of a Lubin-Tate extension of . As an application, we show that if is a totally real number field and is a place of lying above , then the -adic representation of associated to a finite slope overconvergent Hilbert eigenform which is -analytic up to a twist is Lubin-Tate trianguline. Furthermore, we determine a triangulation in terms of a Hecke eigenvalue at . This generalizes results in the case obtained previously by Chenevier, Colmez and Kisin.
