Participating Seminar in Topology (Winter 2002, Spring 2002, Fall 2002) Robert Brown

The regular attendees were four members of the regular faculty (Robert Brown, Rodolfo De Sapio, Robert Edwards and Geoffrey Mess), two postdoctoral quests (Daniel Gottlieb from Purdue and Philip Martens formerly of USC) and five graduate students (John Ahl, Joel Better, Chan-Ho Suh, Zhiqing Yang, Peter Yi) who gave the majority of the presentations. The contents of the talks were determined by the interests of the speakers and thus ranged over many topics from both algebraic and geometric topology.

Course Announcement:

Organizer: Robert Brown

If you've been wondering what sort of topology (and some geometry too, the boundaries aren't well-defined) is of interest to the people in this department, here's your chance to find out. The topics will vary from week to week. As is customary in this seminar, the level of exposition will range from rather elementary to rather incomprehensible, sometimes within a single talk. There are no prerequisites and everyone is welcome.

First talk, Oct. 2: Robert Brown "Period three implies chaos".
