Number Theory-Volume I.Tools and Diophantine Equations

Graduate Texts in Mathematics 239This book deals with several aspects of what is now called “explicit number theory,” not including the essential algorithmic aspects, which are for the most part covered by two other books of the author [Coh0] and [Coh1]. The central (although not unique) theme is the solution of Diophantine equations, i.e., equations or systems of polynomial equations that must be solved in integers, rational numbers, or more generally in algebraic numbers. This theme is in particular the central motivation for the modern theory of arithmetic algebraic geometry. We will consider it through three of its most basic aspects. The first is the local aspect, The second aspect is the global aspect, The third aspect is the theory of zeta and L-functions.
