Our special topics seminars will be normally held on Friday afternoons at 3:30 PM in the Myers Seminar Room. To access the list of topics to be covered, download the schedule. Visitors are always welcome.

The schedule for this year's group meetings has not yet been posted. We shall do our best to post it as soon as possible.
