A. Kurzmann,S. Butzer,T. Bohlenribed in Chapter 1 and the finite simplicial complexes which we shall construct in Chapter 6 in order to triangulate spaces. 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

A. Kurzmann,S. Butzer,T. Bohlenhe points of .. 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 Möbius 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

Identification Spaces, of the Möbius strip in more detail and explain how to use the topology of the rectangle in order to make the Möbius strip into a topological space. The Möbius strip, when defined in this way, will be an example of an ..
