Abstract

Let FF be a non-archimedean local field. For any irreducible representation π\pi of an inner form G=GLm(D)G'=\mathrm{GL}_{m}(D) of G=GLN(F)G=\mathrm{GL}_{N}(F), there exists an irredubile representation of a maximal compact open subgroup in GG' which is also a type for π\pi. Then we can consider the problem whether these types are unique or not in some sense. If such types for π\pi are unique, we say π\pi has the strong unicity property of types. On the other hand, there exists a correspondence connecting irreducible representations of GG' and GG, called the Jacquet--Langland correspondence. In this paper, we study the ralation between the strong unicity of types and the Jacquet--Langlands correspondence.
