Foundations of Mathematical Analysis covers a wide variety of topics that will be of great interest to students of pure mathematics or mathematics and philosophy. Aimed principally at postgraduates and well-motivated undergraduates, its primary concern is a discussion of the fundamentalnumber systems, $Bbb N$, $Bbb Z$, $Bbb Q$, $Bbb R$, and $Bbb C$, in the context of the branches of mathematics for which they form a starting point; for example, a study of the natural numbers leads on to logic (via G"odel's theorems), and of the real numbers (as constructed by Cauchy) tometric spaces and topology. Prof. Truss offers a refreshingly original approach to these matters, presenting standard material in new ways, and incorporating less mainstream topics such as long real and rational lines and the p-adic numbers. With a discussion of constructivism and independencequestions including Suslin's problem and the continuum hypothesis, Prof. Truss completes a wide-ranging consideration of the development of mathematics from the very beginning, concentrating on the foundational issues particularly related to analysis. The book is presented in such a manner as to beaccessible to non-specialists.
