Lectures on Elementary Number Theory

Based on a series of lectures at Haverford College, Hans Rademacher presents an accessible introduction to number theory. Requiring no prior knowledge of the subject, the text covers foundational theorems like prime factorization and quadratic reciprocity, detailed cyclotomy, and Gaussian sums. It addresses analytic number theory through asymptotic laws, Dirichlet’s theorem on primes in an arithmetical progression, and V. Brun’s twin prime theorem. Rademacher’s unique approach integrates an...
