Explicit local Jacquet-Langlands correspondence: the non-dyadic wild case

Abstract

Let $F$ be a non-Archimedean locally compact field of residual characteristic $p$ with $p\ne 2$. Let $n$ be a power of $p$ and let $G$ be an inner form of the general linear group ${\text{GL}}_n(F)$. We give a transparent parametrization of the irreducible, totally ramified, cuspidal representations of $G$ of parametric degree $n$. We show that the parametrization is respected by the Jacquet-Langlands correspondence, relative to any other inner form. This expresses the Jacquet-Langlands correspondence for such representations within a single, compact formula.
