Rings and modules published in was designed for instructors rather than for students. Ribenboim points out in the Preface that he considers preparation of exercises as well as expansion of material to be roles of a competent instructor.

Jacobowitz, in a review of the work, writes: Instead of the customary material on paulo ribenboim factorization and unit theorems, the reader will find such topics as p-adic logarithms, the Witt ring, infinite Galois theoryordering of number fields and diophantine dimension including Terjanian's celebrated counterexample.

The author possesses an excellent feeling for the precise amount of detail needed in a proof, which makes much of the paulo ribenboim accessible even at the advanced undergraduate level.

There are many exercises of a theoretical, rather than routine computational, nature which complement the text. In short, the author has written an attractive exposition of paulo ribenboim subject.


Also in paulo ribenboim published Algebraic numbers. The book is divided into 13 chapters, the first four of which provide background material.

The next six chapters cover algebraic integers, integral basis, discriminantthe paulo ribenboim of ideals in Dedekind domains, the norm of an ideal, finiteness of the class number, the structure of the group of units, the ramification index and the degree of inertia, discriminant and different.

Chapters 11 and 12 treat more specialised topics.

The first of these is paulo ribenboim to ramification theory in Galois extensions and the second to a proof of the theorem by Kronecker and Heinrich Weber on the abelian extensions of the field of rational numbers. Many people will think of Ribenboim as a writer of superb number theory paulo ribenboim.


He began to write about paulo ribenboim topic, one which clearly had an enormous fascination paulo ribenboim him, in with his famous text 13 lectures on Fermat's last theorem. Further wonderful books of number theory have excited many students and turned them on to mathematics. The book of prime number records published in has six chapters entitled: How many primes are there?

A reviewer's comment "This book is well written with much wit" certainly applies to this book, but could equally apply to all of Ribenboim's books.

Another classic is The little book of big primes which is an abridgement of the book paulo ribenboim described. It has a sequel: The little book of bigger primes 2nd edition, Further number theory books are Catalan's Conjecture published inThe paulo ribenboim book of prime number records and Fermat's last theorem for amateurs More recent books by Ribenboim are: The theory of classical valuations ; My numbers, my friends ; Classical theory of algebraic numbers In the Preface to the first of these Ribenboim explains the what he intends to study: OstrowskiHasseSchmidtand others developed this theory.

These are the classical valuations which are the object of this book.


Krull extended the concept of a valuation of a field, by allowing the values to be in any totally ordered abelian additive group. Such valuations are often called Krull valuations; the classical valuations are special Krull valuations. In this book we paulo ribenboim not study Krull valuations.

In addition to writing many books, Ribenboim has edited a number paulo ribenboim 'Collected Works' of his fellow mathematicians.
