| Research Abstract |
We applied the framework of the eDL correspondence [1,2] to construct a geometric model of tempered representation of affine Hecke algebras of classical types, which is continuous with respect to the parameter deformation [3]. By putting this technique further, we established an algorithm to compute the discrete series characters of affine Hecke algebras of classical types, which interpolates various parameters and types [5]. As an application, we determined the constant in the formal degree formula of affine Hecke algebra, which was left from the study of Opdam and Solleveld. This finalizes the computation of the Plancherel measure of affine Hecke algebras of classical types. In addiction, modulo the result of Bushnell-Henneirt-Kuszko, our result (is supposed to) completes the computation of the Plancherel measure of p-adic groups of classical types.
