Abstract
Let be a non-archimedean local field and be a connected reductive group over . For a Bernstein block in the category of smooth complex representations of , we have two kinds of progenerators: the compactly induced representation of a type , and the parabolically induced representation of a progenerator of a Bernstein block for a Levi subgroup of . In this paper, we construct an explicit isomorphism of these two progenerators. Moreover, we compare the description of the endomorphism algebra for a depth-zero type by Morris with the description of the endomorphism algebra by Solleveld, that are described in terms of affine Hecke algebras.
