Ninth Copper Mountain Conference
Multigrid Methods
APRIL 11-16, 1999

This program is preliminary and subject to modifications.
Times given here are only estimates, and are likely to change.
We will try to limit most schedule changes to within the given day.
Participants and speakers should monitor this page and the bulletin board at the conference.
Speakers should plan their talks to be at most 20 minutes.
Program Chairs will adhere strictly to this schedule.
We will have a slide projector and an overhead projector for speaker use. We will also provide an In Focus Systems Lite Pro 620 multimedia projector, which plugs into standard video outlets on a Mac or PC to project its image onto the screen. This equipment will also be available for the special evening sessions.
Wednesday night's cash bar & banquet is in Victoria B in the Pavillon.
All other activities will be held in the Village Square conference facilities.
