Hello everyone!
For those of you who have in-person classes right before or after this seminar and would like for this reason to follow the online sessions while on campus, in the following website you can find some suggestions for rooms which you can have Zoom sessions in (with or without reservation). Sadly, I found out that the offer of special Zoom rooms in the main library has been discontinued this semester, but there is an abundance of other rooms. Give them a try and if these don't work either, we'll find some other solution.
