Abstract |
|
In this paper we study cohomology theories on a space X with supports in a family of supports Φ. There is a uniqueness theorem asserting that a homomorphism between two cohomology theories on the space X with the same family of supports Φ which is an isomorphism for every A ∈ Φ is an isomorphism for every closed set A ⊂ X. |
