Recipes to compute the algebraic K-theory of Hecke algebras of reductive p-adic groups (2306.01510v3)
Published 2 Jun 2023 in math.KT and math.RT
Abstract: We compute the algebraic K-theory of the Hecke algebra of a reductive p-adic group G using the fact that the Farrell-Jones Conjecture is known in this context. The main tool will be the properties of the associated Bruhat-Tits building and an equivariant Atiyah-Hirzebruch spectral sequence. In particular the projective class group can be written as the colimit of the projective class groups of the compact open subgroups of G.
