Abstract The purpose of this chapter is to provide the theoretical background for a rigorous discussion of knots and surfaces, against which the vaguely expressed ideas lying behind our previous discussion can be made precise. The central notion is that of a topological space.

General Topology Topological Spaces
1987The purpose of this chapter is to present very rapidly some of the basic, concise results in general topology – mostly without proofs. The reader interested in this topic may consult the works of N. Bourbaki, J. L. Kelley and K. Kuratowski for a detailed account.

In terms of neighborhood filters with bases composed of open sets, closed sets, regular-open sets or regular-closed sets and the intersection of these filters, the authors define separation type properties \(M_ 1\), \(M_ 2\), \(M_{2.5}\), \(M_ 3\), as well as some strong or weak variations, in terms of the intersection of these filters.

Abstract In this chapter, we make our final leap into generality: we introduce topological spaces as our ultimate framework for studying continuity. At the end of the last chapter we saw that the open sets in a metric space are the most important elements when defining continuity.
