  Incoming and Local
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.

The other event hosted by the group is an informal brown-bag lunchtime discussion and journal club (organized by Reiko Toriumi and Lisa Glaser - send them 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.
