“…In the context of some classes of metric spaces, L p -cohomology is a quasi-isometry invariant with interesting applications to classification problems. This notion is defined, for example, for simplicial complexes [7,14,25,21], Riemannian manifolds [18,19,34,31], discrete and topological groups [3,4,5,6,12,30,35,36] and more general metric measure spaces [16,33,36].…”
