Organizers: Peter Dillery, Tom Haines, and Niranjan Ramachandran

When: Monday or Wednesday @ 2pm
Where: generally in MTH 3206, see below

Starting fall of 2021 the seminar will be hybrid. When possible it will be held in person in the Colloquium Room (3206) of the mathematics department. In additition it will be sometimes be available live on Zoom. The password is the first six Fibonacci numbers (starting at 0). University of Maryland users will be admitted directly. Other users should use their first and last names, and will be admitted from the waiting room. In many cases the video and/or slides will be available on this page following the lecture.

In Fall 2023, the seminar will generally be in MTH 3206 except on certain dates when the room is booked for something else; these dates will be announced here.
