Translation functors for locally analytic representations

Abstract

Let GG be a pp-adic Lie group with reductive Lie algebra g\mathfrak{g}. In analogy to the translation functors introduced by Bernstein and Gelfand on categories of U(g)U(\mathfrak{g})-modules we consider similarly defined functors on the category of coadmissible modules over the locally analytic distribution algebra D(G)D(G) on which the center of U(g)U(\mathfrak{g}) acts locally finite. These functors induce equivalences between certain subcategories of the latter category. Furthermore, these translation functors are naturally related to those on category O\mathcal{O} via the functors from category O\mathcal{O} to the category of coadmissible modules. We also investigate the effect of the translation functors on locally analytic representations Π(V)la\Pi(V)^{\rm la} associated by the pp-adic Langlands correspondence for GL2(Qp){\rm GL}_2(\mathbb{Q}_p) to 2-dimensional Galois representations VV.
