Abstract

Let p>3p>3 and FF be a non-archimedean local field with residue field a proper finite extension of Fp\mathbb{F}_p. We construct smooth absolutely irreducible non-admissible representations of GL2(F)\mathrm{GL}_2(F) defined over the residue field of FF extending the earlier results of the authors for FF unramified over Qp\mathbb{Q}_{p}. This construction uses the theory of diagrams of Breuil and Paskunas. By parabolic induction, we obtain smooth absolutely irreducible non-admissible representations of GLn(F)\mathrm{GL}_n(F) for n>2n>2.
