To the members of the Executive Organizing Committee and Local Organizing Committee of the International Congress of Mathematicians (ICM):

Dear ICM Organizers,

The international mathematical community is deeply concerned about the situation of Azat Miftakhov, the graduate student from Moscow State University who has been detained by Russian state authorities for nearly two years.

Azat is a talented young mathematician who comes from the Tatarstan region in the Russian Federation. Already in school he won prizes in several math competitions and received support given to talented young people by the Ministry of Education and Science. As a student in Moscow he became involved with the anarchist movement. In February 2019, right after his return from a conference in Nizhni Novgorod where Azat gave his first talk in English, he was detained by the police and accused of manufacturing explosives. He was tortured at the police station. After three days Azat was released, since the court found no evidence to justify his detention. Less than two days later, on February 9, 2019, he was again arrested and accused of destruction of an office window of the United Russia political party, an act which had taken place more than a year earlier. He has been kept in jail since then. The lack of evidence in Azat’s case is disturbing, as is the fact that, for most of the time since his arrest, he has remained in pre-trial detention.

Azat pleads not guilty. During his detention he has managed to publish two mathematical preprints on arxiv.

Azat Miftakhov has been recognized as a political prisoner by the Russian human rights organization Memorial. The American Mathematical Society and Société Mathématique de France have issued statements of concern. A recent petition in support of Azat has been signed by more than 2000 mathematicians from more than 15 countries.

On December 23, 2020 it was announced that Azat faces six years of prison if convicted.

While Russia is going to host the ICM in less than two years, Miftakhov’s trial reminds us of the host country’s frequent violations of human rights and repression of freedoms, which are regularly condemned by human rights organizations. Let us recall that in 1982 the International Congress in Warsaw was postponed by one year, during which various actions were taken by the international mathematical community to free political prisoners in Poland.

Freedom is one of the highest values for us as scientists. Attending the congress while our colleague Azat Miftakhov is arbitrarily detained will pose a serious dilemma for us and for the entire mathematical community. We kindly ask you to take an active position on this case and to communicate with the state authorities to free Azat.
