Elementary Number Theory

Free eBook “Elementary Number Theory: Primes, Congruences, and Secrets: A Computational Approach” by William Stein. This is a textbook about classical elementary number theory and elliptic curves. The first part discusses elementary topics such as primes, factorization, continued fractions, and quadratic forms, in the context of cryptography, computation, and deep open research problems.

Description

The second part is about elliptic curves, their applications to algorithmic problems, and their connections with problems in number theory such as Fermats Last Theorem, the Congruent Number Problem, and the Conjecture of Birch and Swinnerton-Dyer. The intended audience of this book is an undergraduate with some familiarity with basic abstract algebra, e.g. rings, fields, and finite abelian groups.

Contents

  • Prime Numbers
  • The Ring of Integers Modulo n
  • Public-key Cryptography
  • Quadratic Reciprocity
  • Continued Fractions
  • Elliptic Curves
