Rational and integral points on higher dimensional varieties

December 11 to December 20, 2002

at the

American Institute of Mathematics, San Jose, California

organized by

Bjorn Poonen and Yuri Tschinkel

Original Announcement

This workshop will be devoted to the study of rational and integral points on algebraic varieties, primarily those of dimension at least two.

We are bringing together researchers in algebraic geometry, diophantine approximation, cohomological methods (e.g. the Brauer-Manin obstruction, universal torsors), analytic methods (e.g. the circle method), and algorithmic arithmetic geometry. We hope especially to facilitate communication between researchers studying theoretical aspects and those with a more computational bent.

The main questions to be addressed concern
