Characteristic Classes,ps .→ .(.)of . into the classifying space .(.) for .(.)-bundles. If ξ, η are two .(.)-bundles with classifying maps ., .→.(.), then . ≃ ηif and only if . ≃.. Suppose we wanted to prove ξ, η were . isomorphic. We might try to show that ., and . were not homotopic. There are two disadvantages to this

Cohomology Operations and Homology Cooperations,geometric problems (existence or non-existence of maps .→.) into algebraic problems (existence or non-existence of .(.)-module homomorphisms with given properties). If one is trying to show the non-existence of a map .: . → . with certain properties, then one wants to show that no homomorphism .*:.*

The Steenrod Algebra and its Dual, were known as much as fifteen years before .*(.), for example, we shall see that the calculation of these Hopf algebras is at least as difficult as the calculation we just did for .. In theory we could proceed as follows: for each . we have a fibration .(ℤ.,.-1) → .(ℤ., .) → .(ℤ., .), and the total
