-Complexes,might hope to construct maps step by step, extending them over the building blocks one at a time. In this chapter we describe a useful category of such spaces (.-complexes) and display some of their elementary properties. In the next chapter we shall prove some much deeper homotopy properties of .-complexes.

Manifolds and Bordism,t of the book (it is recommended that the reader unfamiliar with the theory of manifolds see [69] or [52]). Instead we go on to define the Thorn complex of a vector bundle and the various Thorn spectra .. Then we sketch the proof of Thorn that the homology theories associated with these spectra can be described in terms of singular manifolds.
