Discriminant Equations in Diophantine Number Theory

Jan-Hendrik Evertse works in the Mathematical Institute at Leiden University. His research concentrates on Diophantine approximation and applications to Diophantine problems. In this area he has obtained some influential results, in particular on estimates for the numbers of solutions of Diophantine equations and inequalities.

The first comprehensive and up-to-date account of discriminant equations and their applications. For graduate students and researchers.
