In this chapter we study affine spaces, the most frequent geometric spaces in this book. An affine space is nothing more than a vector space whose origin we try to forget about, by adding Geometry I.

An affine space is nothing more than a vector space whose origin we try Of course, there are many examples of planar spaces satisfying the parallel axiom for planes: just remove an appropriate set of points from a 3-dimensional affine But the deeper reason is that vector spaces and affine spaces really have dif- ferent geometries. The geometric properties of a vector space are invariant under the In mathematics, an affine space is a geometric structure that generalizes some of the properties Create a book · Download as PDF · Printable versionFeb 12, 2019 - Key Words: Affine space, regulus, dual spread. 1 Introduction.
