**Organizers: **Harry Tamvakis, Tom Haines, Jeffrey Adams**When:** Mondays or Wednesdays @ 2pm**Where:** Online for fall 2020**Pre-2012 Archives:** Spring 2012 | Fall 2011 | Spring 2011 | Fall 2010 | Spring 2010 | Fall 2009 | Spring 2009 | Fall 2008

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.

This year's **Maryland Distinguished Lectures in Algebra and Number Theory**** **are being give by Wei Zhang, December 1-3, 2021.

Videos and Slides fall 2021 to spring 2022:

- Jeffrey Adams, September 22: Arthur and ABV packets
- Jeffrey Adams, September 29: Arthur and ABV packets II
