Organizers: Tom Haines, Niranjan Ramachandran and Yihang Zhu
When: Monday or Wednesday @ 2pm

Where: ONLINE for fall 2020. 

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 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.
