-Complexes,ological spaces. One of the difficulties is that given two arbitrary topological spaces . it is very difficult to construct any map .: . → .. If we restricted our attention to a class of spaces built up step by step out of simple building blocks (think of simplicial complexes, for example), then we

We shall show that any two ordinary homology theories with coefficients . satisfying the wedge and WHE axioms are naturally equivalent. We shall also construct the Eilenberg-MacLane spectrum . with

Vector Bundles and ,-Theory,ose for which every fibre has the structure of a vector space in a way which is compatible on neighboring fibres. We show how equivalence classes of such vector bundles over a .-complex can be used to define groups .*(.) in such a way that .* becomes a cohomology theory.

Products,homology functors: one wants to investigate the existence or nonexistence of maps .: . → . by looking at the corresponding algebraic morphisms .:.(.) → .(.). As we have said before, the richer the algebraic structure on .(.), the more useful . will be for these investigations. In this chapter we int
