What is Trivial Notions?

The Trivial Notions seminar is held once a week in the Mathematics Department at Harvard University. The target audience is the graduate student body of the Department, and those giving talks are (almost always) graduate students in the Department. Talks can be on any topic, but they should be accessible to graduate students!

The seminar is a great way to find out what other students are thinking about. It's also a great way to practice talking mathematics in front of others, without the distraction of scary professors in the audience.

This is an archive page. The current Seminar announcements are here. There are still some few blank spots in this archive. If you were organizing trivial notions or gave a talk in this series, or some of the reconstructed seminar titles need correction, please send details to webmaster@math.
