Our regular slot for seminars on quantum gravity and other interesting topics is
on Fridays at 14.00h. The venue is HG02.802, unless specified otherwise.
UPDATE Seminars are currently taking place remotely on Fridays at 14.30h.
If you are not on one of our distribution lists for the announcements, please contact
R. Loll for log-in details if you would like to participate in a specific event.
The other event hosted by the group is an informal brown-bag lunchtime discussion and journal club
(currently organized by Timothy Budd - send him an email if you want to join the mailing list)
which takes place on Wednesdays at 12.30h in room
HG02.802, unless specified otherwise. UPDATE Also these seminars are currently
happening online, usually on Wednesday at 14.30h. The schedule can be found
here.
