| Feb 24, 2010 at 16:44 | comment | added | HenrikRüping | but I think there are also homology theories, wehre this map is not an isomorphism. In this situation homology with compact support could make sense/be useful. | |
| Feb 24, 2010 at 15:39 | comment | added | Andrea Ferretti | It seems they define homology with compact support as the direct limit of homology of compact subspaces. But this is just the ordinary homology (if we are considering singular homology), since every singular chain is contained in some compact subspace anyway (so the natural map between the direct limit and the ordinary homology is an isomorphism). | |
