We shall show that one can characterize these subsets by a purely topological property, that is to say a property which involves only the topological structure of E. and makes

We have already made use of this process: in Chapter 1 we had occasion to construct various surfaces and we showed how to obtain the M?bius strip, the torus, and the Klein bottle by making appropriate identifications of the edges of a rectangle. We propose to examine the construction

The fundamental group is a very valuable tool, but it has a significant defect. Remember that the fundamental group of a polyhedron depends only on the 2-skeleton of t
