IGAP Geometry and Physics seminar 04/05 (change in time)

[Christian]

Dear everyone,

To avoid overlaps with teaching duties we have decided to start the 
seminar one hour earlier so:

*Tuesday May 4th at 10:00 (notice even earlier time)*

The Zoom link will be the same:

The meeting will be on Zoom at the following coordinates:
