This is a list of future online talks in combinatorics. There is also a mailing list, to which we will email this week's activities, perhaps twice a week. If you would like to be added or removed from the list, please send email to pds@math.princeton.edu with a university email address, or a one-line description of who you are.

If you have a talk that you would like to be listed here, please send to Paul Seymour (pds@math.princeton.edu) the title, day, time and time-zone, name and affiliation of the speaker, name of hosting institution, the link to join the meeting, and a link to the abstract (not the abstract itself). If you let us know the password, we will mail it out to the people on the mailing list.
