Introduction to Analytic Number Theory

Detailed Summary of the Book

The primary focus of Introduction to Analytic Number Theory is the study of the properties of integers through the lens of analysis. It introduces key concepts like arithmetic functions, the structure of integers, and the use of analytical techniques like summation methods, asymptotic evaluations, and estimates to reveal deeper insights into number-theoretic problems. Beginning with an accessible discussion of elementary properties of integers, the text gradually progresses toward advanced topics such as the Dirichlet characters and primes in arithmetic progressions.

The early chapters establish foundational tools, defining and exploring arithmetic functions like the divisor function and the Möbius function, as well as techniques such as Möbius inversion and partial summation. These concepts are applied to classical problems and theorems, including the distribution of prime numbers and Euler's totient function. The book further explores the Riemann zeta function, an essential object in analytic number theory, unveiling its profound implications and connections to other areas of mathematics.

Key sections also include in-depth discussions of Dirichlet's theorem, which proves the infinitude of primes in arithmetic progressions. Apostol masterfully bridges elementary number theory with analytic methods, thereby offering the student both theoretical understanding and practical techniques used in research. The book concludes with chapters on advanced topics such as partitions and quadratic forms, providing a rich and comprehensive perspective on the subject.
