Virtual Combinatorics Seminars
On this page you will find a list of seminars (mostly combinatorics, some discrete geometry) arranged by days and times, which frequently change so please double-check the seminar websites.
Although some of these seminars have gone back to in-person, the recorded talks when they were virtual are still available at the links.
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.
