Kuznetsov's arrest is a depply shameful moment for the Russian authorities, and ought to make the organisers of the 2022 ICM strongly reconsider.

At least nine ICM2022 committee members have already signed this petition - please encourage others to join our community effort to free one of our most prominent Russian colleagues!

With grave concern I heard about the news of the arrest of the mathematician Alexander Kuznetsov -- winner of the European Mathematical Society prize of 2008 -- after preacefully protesting the detention of Alexey Navalny. I ask that he - and other peaceful protesters - be freed immediately.

As a fellow mathematician I condemn dictator Putin's repression against Prof. Kuznetsov, other colleagues, and the brave russian people in general who participated in the peaceful protest supporting Mr. Navalny.

He should make a lecture in my faculty on 10 february. Also Azat Miftakhov, a PhD student was arrested for political reasons with false accusations. Silencing the expression of political ideas is a crime, and all governemnt should step forward to denounce it.

This is an outrage - Professor Kuznetsov is a mathematician with a huge international profile and Russia will severely damage its scientific reputation with this kind of behaviour. He must be released immediately.

Free not only Alexander Kuznetsov but also other peaceful protesters

We, late citizens of communist countries know how diifficult it may be to take courage and supports oponents of regime. That's why I admire him and feel duty to sign thispetition.
