The book is based on a course given by J.-P. Serre at the Collège de
France in 1980 and 1981. Basic techniques in Diophantine geometry are
covered, such as heights, the Mordell-Weil theorem, Siegel's and Baker's
theorems, Hilbert's irreducibility theorem, and the large sieve.
Included are applications to, for example, Mordell's conjecture, the
construction of Galois extensions, and the classical class number 1
problem. Comprehensive bibliographical references.
