Number Theory IV: Transcendental Numbers

Detailed Summary of the Book

This book provides a comprehensive exploration of the theory of transcendental numbers, which are those numbers that cannot be the root of any non-zero polynomial equation with rational coefficients. Classic examples include numbers like π (pi) and e. "Number Theory IV" not only systematically develops the foundational results in this field but also addresses some of the most advanced topics and unsolved problems, making it valuable for both beginners and advanced researchers.

The authors begin with an introduction to algebraic and transcendental numbers, laying down the groundwork for readers unfamiliar with these topics. This includes discussions on Liouville’s theorem, algebraic independence, and the Hermite–Lindemann–Weierstrass theorem. From there, the book progresses to more intricate subjects such as transcendence measures, Gelfond–Schneider methods, and applications of Baker's theory.

Particular emphasis is given to effective methods in transcendental number theory, where theoretical results meet computational techniques. Additionally, the text explores connections between transcendental numbers and other areas of mathematics, such as Diophantine approximations and the geometry of numbers. By presenting numerous examples, proofs, and problems, the book remains highly illustrative and instructive throughout.
