A Jacquet-Langlands functor for $p$-adic locally analytic representations

Number Theory 2026-05-12 v3 Representation Theory

Abstract

We study the locally analytic theory of infinite level local Shimura varieties. As a main result, we prove that in the case of a duality of local Shimura varieties, the locally analytic vectors of different period sheaves at infinite level are independent of the actions of the pp-adic Lie groups GG and GbG_b of the two towers; this generalizes a result of Pan for the Lubin-Tate and Drinfeld spaces for GL2\mathrm{GL}_2. We apply this theory to show that Scholze's pp-adic Jacquet-Langlands functor commutes with the passage to locally analytic vectors, and is compatible with central characters of Lie algebras. We also prove that the compactly supported de Rham cohomology of the two towers are isomorphic as smooth representations of G×GbG\times G_b.
