## Diophantine equations: The geometric approach.(English)Zbl 0863.14012

This is a survey on the study of diophantine equations, with emphasis on those methods that make use of the geometry of an underlying algebraic variety. In addition, the survey emphasizes the study of rational (as opposed to integral) solutions. Topics covered include lifting (of rational points to one of a finite set of covering varieties); the Hasse principle and Brauer-Manin obstruction; modular curves and the Taniyama-Shimura conjecture; the Birch-Swinnerton-Dyer conjecture; and conjectures of Manin and others on the density of rational points.
