Virtual Combinatorics Seminars

On this page you will find a list of seminars (mostly combinatorics, some discrete geometry) arranged by days and times, which change so please double-check the seminar websites. This is not an exhaustive list. Although some of these seminars have gone back to in-person, the recorded talks when they were virtual are still available at the links.

If you are interested in combinatorics seminars, you may want to sign up for weekly announcements as indicated on the Combinatorics Lectures Online webpage maintained by Jacob Fox and Paul Seymour. A very large list of math seminars is available at www.mathseminars.org and CS Theory talks are available here.

Additionally, take a look at this amazing Round the World Relay in Combinatorics.

All times below are Eastern Standard Time (ET). If you are planning a new seminar, you may find this list useful to avoid clashing with existing seminars.
