Controlled Topology Methods
摘要
In this chapter we explain and prove in detail for any group G and any G-CW- complex X what we have briefly discussed in Subsection 19.4.5.We will allow more general coefficients than rings or additive G-categories, namely, categories with G-support, see Definition 21.1. This notion seems to be the most general one and illustrates nicely what is needed to successfully establish the desired constructions and theorems appearing in this chapter.
