The Theory of Numbers: A Text and Source Book of Problems

The Theory of Numbers: A Text and Source Book of Problems serves as both a comprehensive textbook and problem collection for undergraduate number theory courses. The book covers fundamental concepts including divisibility, prime numbers, congruences, and quadratic reciprocity. Each chapter contains detailed explanations of key theorems and mathematical concepts, followed by extensive problem sets at multiple difficulty levels. The problems range from basic computational exercises to more advanced proofs and applications. The text includes historical notes on the development of number theory and biographical information about mathematicians who made major contributions to the field. References and citations throughout connect the material to broader mathematical literature. This book balances theoretical rigor with accessibility, making abstract number theory concepts concrete through careful exposition and well-chosen examples. The emphasis on problem-solving provides students with tools to explore and discover mathematical patterns independently.

There are not enough internet reviews to create a summary of this book. Instead, here is a summary of reviews of Carl Pomerance's overall work: Students and researchers comment frequently on Pomerance's textbook "Prime Numbers: A Computational Perspective," praising its clear explanations of complex algorithms and comprehensive coverage of computational number theory. What readers liked: - Clear presentation of advanced mathematical concepts - Practical implementation details for algorithms - Balance between theory and computation - Extensive bibliography and historical notes What readers disliked: - Dense mathematical notation that can be challenging for beginners - Some sections require significant background knowledge - High price point for the textbook Ratings: - Goodreads: 4.5/5 (12 ratings) - Amazon: 4.7/5 (8 reviews) One graduate student noted: "The sections on primality testing are exceptional - they break down complex algorithms into digestible steps." A researcher commented: "The historical context helps connect theoretical concepts to practical applications." Readers particularly value the exercises and computational examples that accompany theoretical discussions.
