The workshop starts on Sunday, January 17, 1999, at 2 p.m. and will continue until approximately 5 p.m. that day. The following days, Monday through Friday, January 22, it will begin each day at 9:30 a.m. and continue until approximately 5 p.m.

The workshop is co-sponsored by the Institute and the Annals of Mathematics.

The main subject of the workshop will be the new computer-assisted proof of the Kepler Conjecture by Tom Hales. (The Kepler Conjecture asserts that the densest packing of Euclidean three space by non-overlapping spheres of identical size is the one we all expect.) Most of the talks and working sessions will be organized and scheduled during the workshop, and will be on this subject.

Lectures will take place in the Simonyi Hall Seminar Room unless notified to the contrary. Every day at 2 p.m. there will be a more formal lecture on related subjects as follows:
