Linear algebra, and the elementary concepts associated with linear spaces. In this chapter we review these ideas, largely to fix terminology and notation. Readers wishing to improve their acquaintance with any part of linear algebra, or to pursue in greater depth any of the topics discussed below, might consult . Another excellent source is .

Die Flexibilisierung des SixpackThe root idea in all that follows is that of “closeness” as between two points of a space. This idea turns out to be elusive and difficult to pin down in general, but it presents no difficulty at all if one is given a numerical gauge for measuring how close together two points are, and that is the case of interest in the present chapter.
