The team's weekly seminar is currently held online every Thursday at 10am (unless specified otherwise); this will be changed to 10.15am or 10.30am starting January 2021 for a better compatibility with the teaching schedule.
The scheduled seminars appear in the team's calendar as soon as they are confirmed (and sometimes even before that): https://framagenda.org/index.php/apps/calendar/p/sfe4BmNwEbKfACJZ/GdT-Lo.
Seminars are also announced on the LIPN website and by email around a week in advance.
The url to the BBB room of the seminar is: https://bbb.lipn.univ-paris13.fr/b/sei-eer-t24 (access code: 749983)
Online seminars are recorded, so the above page also gives access to the recordings of past talks.
