Quasi-isometry invariance of cohomological dimension. (English. Abridged French version) Zbl 0805.20043

Summary: The groups \(H^ n(G,RG)\) are quasi-isometry invariants for all rings \(R\) and groups \(G\) possessing a \(K(G,1)\) which has finitely many cells in dimensions at most \(n\). It follows that the cohomological dimension is a quasi-isometry invariant for groups \(G\) admitting a finite \(K(G,1)\) complex.
