Beschreibung
There are numbers of all kinds: rational, real, complex, p-adic, and more. The p-adic numbers are not as well known as the others, but they play a fundamental role in number theory and in other parts of mathematics, capturing information related to a chosen prime number p. They also allow us to use methods from calculus and analysis to obtain results in algebra and number theory.
This book is an elementary introduction to p-adic numbers. Most other books on the subject are written for more advanced students; this book provides an entryway to the subject for students with an undergraduate mathematics education. Readers who want to have an idea of and appreciation for the subject will probably find what they need in this book. Readers on the way to becoming experts can begin here before moving on to more advanced texts.
This third edition has been thoroughly revised to correct mistakes, make the exposition clearer, and call attention to significant aspects that are usually reserved for advanced books. The most important addition is the integration of mathematical software for computations with p-adic numbers and functions. A final chapter includes a selection of problems for further exploration.
From the reviews of the first and second editions:
"Perhaps the most suitable text for beginners" - The Mathematical Gazette
"This text perfectly fulfills what it proposes" - Mathematical Reviews
"An extraordinarily nice manner to introduce the uninitiated to the subject" - Mededelingen van het wiskundig genootschap
"If I had to recommend one book on the subject to a student – or even to a fully grown mathematician ...– it would still be this book" - MAA Reviews

“This book was intended to be for undergraduates and it was really an excellent place to start, with a good choice of subjects and many exercises, and this third edition is even better. … It is really an excellent book with a vivid style, pleasant to read, with 360 exercises going from easy computations by hand of an example to more advanced conceptual or computational exercises.” (Daniel Barsky, Mathematical Reviews, March, 2022)
