Constructions of Topological Spaces, seen this in the study of vector space structure. The same is true for topological spaces. This yields important new spaces (for example, the tori ..; cf. also the projective spaces, in the exercises for Chapter IV).

Compact Spaces,uitful definition (see the properties of compact spaces in §§2 and 3, and the applications in nearly all the rest of the course). In §4, we adjoin to the real line . a point + ∞ and a point − ∞ so as to obtain a compact space, the ‘extended real line’ ̅.; the student has made use of this for a long

Limits of Functions, tend simply, to a function .. In this chapter we study these concepts in the general setting of metric spaces. We obtain in this way certain of the ‘infinite-dimensional’ spaces alluded to in the Introduction, and, thanks to Ascoli’s theorem, the . of these spaces.

Normed Spaces,ms. In §§6, 7, 8 we make the connection between this theory and that of complete spaces; some of these results (Banach-Steinhaus theorem, Riesz’s theorem) are very fruitful, but the reader can hardly be convinced of this unless (s)he studies ‘functional analysis’ later on.

Connected Spaces,istinguish, by various methods, those spaces that are ‘in one piece’ (for example a disc, or the complement of a disc in a plane) and those which are not (for example, the complement of a circle in a plane).
