From PL to Sheaf Theory (Rock to Bach),each entitled to have our own preference in music. But let’s not forget that to the original geometers, homology was not a derived functor on the category of sheaves, nor a functor from spaces to groups satisfying axioms 1–7. Homology was space itself, space with multiplicities.

Les Foncteurs de la Categorie des Faisceaux Associes a Une Application Continue,ie des faisceaux de A-modules, notés f., et f., qui permettent de déterminer une dualité de Poincaré pour les espaces localement compacts. L’actualité de ces foncteurs, connus et utilisés depuis longtemps en géométrie algébrique (voir [.]), provient du fait qu’ils interviennent dans la théorie de la cohomologie d’intersection (voir [.]).

Problems and Bibliography on Intersection Homology,.]. For a small resolution π: . there is a canonical isomorphism .. We might expect other “intersection functors” to satisfy a similar identity. A severe limitation on the existence of such functors is therefore provided by the existence of spaces which have two different small resolutions.
