Homological stability for completed homology. (English) Zbl 1404.11071

Summary: We prove that the completed homology groups of \(\mathrm{GL}_n(\mathbb {Z})\) in fixed degree stabilize as \(N\) goes to infinity. We also prove that the action of Hecke operators on stable cohomology is trivial, in a precisely defined sense.
