- Seminar meets at 4:40 PM central time on Thursdays on Zoom.
- Organizers: Patty Commins, Libby Farrell, and Trevor Karn. Website maintained by Trevor.
- Past seminar archive: 2019-2020, 2018-2019, 2017-2018, 2016-2017.
- UMN Combinatorics Seminar.
- Three things exercise for getting things out of talks.
- With the goal of humanizing the seminar and getting to know our speakers as people and mathematicians, we've started asking our speakers to dedicate a slide at the beginning of their talk to introduce themselves and their role in the department, and then answer one (or more!) of the following questions:
- What do you do outside of mathematics?
- How did you end up where you are? How did you get started in mathematics?
- What is the best advice you’ve ever received? Who gave it to you?
- Who is one person you look up to? Why do you look up to them?
- What is your proudest accomplishment?
