Abstract:

Let $p>3$ and $F$ be a non-archimedean local field with residue field a proper finite extension of $\mathbb {F}_p$. We construct smooth absolutely irreducible non-admissible representations of $\mathrm {GL}_2(F)$ defined over the residue field of $F$ extending the earlier results of the authors for $F$ unramified over $\mathbb {Q}_{p}$. This construction uses the theory of diagrams of Breuil and Pašk$\bar {\mathrm {u}}$nas. By parabolic induction, we obtain smooth absolutely irreducible non-admissible representations of $\mathrm {GL}_n(F)$ for $n>2$.
