| Jul 17, 2010 at 18:15 | comment | added | Lennart Meier | The following theorem might be relevant: if we have a functor C from finite CW-pairs to chain complexes st. 0 -> C(A) -> C(X) -> C(X,A) -> 0 is short exact and the homology of C is a homology theory, then C represents ordinary homology. This is shown in a paper by Burdick, Conner and Floyd and illustrates that extraordinary homology theories do not fit very well in a classical chain complex context. | |
