There might be just enough time to pick another location, but I am curious what mathematicians think. Will Ukrainian mathematicians be able to attend a conference in Russia if Russia no longer recognizes their passports?
To be clear: I love Russia, and I am not trying to hurt the feelings of Russian mathematicians or people.
The International Mathematical Union (IMU) have made a decision on moving the ICM to a virtual event, but there is still the (less exciting) decision to make concerning the location of IMU General Assembly.
