The compact-open Farrell–Jones conjecture for Hecke categories

About 3 years old · traced to

Let GG be a td-group and let B\mathcal{B} be a Hecke category with GG-support satisfying condition (Reg): for every natural number dd there is a natural number l(d)l(d) such that, for every compact open subgroup U⊆GU\subseteq G, the additive category B[G/U]⊕[Zd]\mathcal{B}[G/U]_{\oplus}[\mathbb{Z}^d] is l(d)l(d)-uniformly regular coherent. The Cop\mathcal{C}\mathrm{op}-assembly map is

HnG(ECop(G);KB)⟶HnG(G/G;KB)=K⁡n(B).H_n^G(E_{\mathcal{C}\mathrm{op}}(G);\mathbf{K}_{\mathcal{B}})\longrightarrow H_n^G(G/G;\mathbf{K}_{\mathcal{B}})=\operatorname{K}_n(\mathcal{B}).

Compact-open Farrell–Jones conjecture. This assembly map is an isomorphism for all nn. This is the paper's main assembly statement for Hecke categories under (Reg); the supplied text gives no resolution evidence.
