Book DetailsThe Carus Mathematical MonographsVolume: 11; 1985; 164 pp
In this monograph, Ivan Niven provides a masterful exposition of some central results on irrational, transcendental, and normal numbers. He gives a complete treatment by elementary methods of the irrationality of the exponential, logarithmic, and trigonometric functions with rational arguments. The approximation of irrational numbers by rationals, up to such results as the best possible approximation of Hurwitz, is also given with elementary techniques. The last third of the monograph treats normal and transcendental numbers, including the transcendence of \(p\) and its generalization in the Lindermann theorem, and the GelfondSchneider theorem.
Most of the material in the first two thirds of the book presupposes only calculus and beginning number theory. The book is almost wholly selfcontained. The results needed from analysis and algebra are central and wellknown theorems, and complete references to standard works are given to help the beginner. The chapters are, for the most part, independent. There is a set of notes at the end of each chapter citing the main sources used by the author and suggesting further reading.

Reviews

The book is fantastic and remains valuable even fifty years after its first appearance. It certainly qualifies (still) as a wonderful choice for a topicsinnumber theory seminar or a tutorial or reading course. Individual chapters of “Irrational Numbers” already go a long way in this regard all by themselves.
