Rational and integral points on higher dimensional varieties

December 11 to December 20, 2002
at the

American Institute of Mathematics,
Palo Alto, 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

- existence of points,
- distribution of points in various topologies, and
- distribution with respect to heights.
