Chapter 1 in Mathematical Analysis, 2004, pp 1-30 from Springer

Abstract: Abstract In this chapter, after an introductory section, in Section 1.2 we shall illustrate the axiomatic approach to real numbers, and, in Section 1.3, we shall identify the natural numbers as the smallest inductive subset of ℝ. Further information about natural numbers will be discussed in Chapter 3, while the notions of sequences and of limit of a sequence, which are specially relevant in mathematics, are discussed in Chapter 2; in Section 2.2 we present, in particular, several equivalent formulations of the continuity axiom.
