Abstract

We extend Urban’s construction of eigenvarieties for reductive groups $G$ such that $G (ℝ)$ has discrete series to include characteristic $p$ points at the boundary of weight space. In order to perform this construction, we define a notion of “locally analytic” functions and distributions on a locally $ℚ_{p}$ -analytic manifold taking values in a complete Tate $ℤ_{p}$ -algebra in which $p$ is not necessarily invertible. Our definition agrees with the definition of locally analytic distributions on $p$ -adic Lie groups given by Johansson and Newton.
