The Fundamental Group,ed spaces. Let . : . → . be a homeomorphism and . be a point of .. Then . is a homeomorphism between pointed spaces (., .) and (., .(.)). The composite of two maps between pointed spaces is again a map between pointed spaces and the identity map . : (., .) → (., .) is always a homeomorphism of pointed spaces for each . ∈ ..

… und was heißt das für die Praxis?to prove the topological invariance of simplicial homology in Chapter 4. This was first done by J.W. Alexander (1888–1971). In a contrast to this, we will see in this chapter that the topological invariance of singular homology follows almost obviously - this is another attractive feature of singular homology.
