Abstract

We define a collapsing or trivialization procedure for bundles over X which yields a bundle over X/A for a closed subset A of X. With this construction we are able to give alternative descriptions of K(X,A) = K(X/A). For a finite CW-pair (X,A) we can define an exact sequence K(A) ← K(X) ← K(X,A) ← K(S(A)) ← K(S(X)), using an appropriate “coboundary operator.” With this sequence we see that in some sense the K-cofunctor can be used to define a cohomology theory.
