The International Mathematical Union must support Azat Miftakhov

The Azat Miftakhov Committee, supported by 321 mathematicians and 4 mathematical societies, sent the following letter to the International Mathematical Union Executive Committee, concerning the case of our colleague Azat Miftakhov. Mathematicians who wish to support this letter can sign it by filling out the form here; an updated list of signatories will be sent to the IMU in a few weeks.

August 23, 2021

Dear members of the International Mathematical Union (IMU) Executive Committee,

On January 5, 2021, we sent you a letter to draw your attention to the case of Azat Miftakhov, a doctoral student in mathematics at Moscow State University, arbitrarily detained by Russian authorities since February 2019.

On January 8, 2021, following our letter, you issued a statement “expressing your deep concern for the well-being of Azat Miftakhov”. “While the IMU cannot know the facts of the case and does not condone acts of vandalism, there has been widely held concern in the media over Miftakhov’s treatment while in custody and over the fairness of the trial and sentencing proceedings, soon to be completed” the statement reads. 

Prof. Carlos E. Kenig, President of the IMU and Prof. Helge Holden, Secretary General of the IMU, wrote on January 11, 2021 to Dr. Daya Reddy, President of the International Science Council (ISC), referring the case of Azat Miftakhov to the ISC, for consideration by its Committee for Freedom and Responsibility in Science.

On January 18, 2021, the Golovinsky District Court in Moscow sentenced Azat Miftakhov to a six-year prison term in a general-regime colony. “Miftakhov’s rehabilitation is possible only in isolation from society in a medium-security penal colony,” the court decided.

On February 26, 2021, you issued a statement about the detainment and arrest of several members of the Russian mathematics community in which you “called for leniency and compassion for Azat Miftakhov as he appeals this sentence.”

On June 9, 2021, the Moscow City Court heard the appeal of the verdict in the case against Azat Miftakhov and it unfortunately upheld Azat’s conviction and six-year prison sentence in a general-regime colony. 

On July 15, 2021, we learned that Azat Miftakhov has been moved from the Moscow pre-trial detention center at Butyrka and began the journey to the penal colony where he is to serve the remainder of his six-year sentence. He has then been moved on August 1st to the correctional colony number 17 in Omutninsk in Kirov Province, which is known for the mistreatment and torture of prisoners by the authorities.

The international mathematical community is appalled and horrified by the arbitrary detention of Azat Miftakhov, the ill-treatment he suffered, including torture, and the verdict inflicted on him. Mathematicians from all over the world have expressed their solidarity with Azat through multiple letters and petitions, including our Russian colleagues whose actions, we all know, can cost them dearly.

The solidarity of the international mathematical community was once again manifested on the occasion of the Azat Miftakhov Day, which we organized on June 16, 2021. The reactions to the event — several renowned mathematicians immediately accepted our invitation to speak, the announcement was quickly relayed by learned societies and prestigious universities around the world, and the event was followed by a large number of colleagues — shows the importance that our community attaches to the case of Azat Miftakhov. 

However, there is one voice conspicuously lacking in its support for Azat’s case, namely yours. Admittedly, you have expressed, in rather conditional terms, your concern regarding the case of Azat. But to our knowledge, you still have not called for his release.

It is now time for the IMU to follow the position adopted by the international mathematical community it represents and to call for the immediate and unconditional release of Azat Miftakhov. As the IMU’s partner in the organization of the next ICM in July 2022 in St Petersburg, the Russian government cannot ignore such a call.

Three senior Russian security officials sit on the ICM Executive Organizing Committee: Dmitry S. Derevyashkin, first Deputy Head of Department “P” of the Economic Security Service of the FSB of the Russian Federation, Aleksey G. Zinin, Deputy Head of the Main Directorate for the Protection of Public Order of the National Guard of the Russian Federation and Roman Yu. Plugin, Head of the Main Directorate of the Ministry of Internal Affairs of Russia for St. Petersburg and the Leningrad Region. It is hard to imagine them attending the opening ceremony of the ICM while our colleague Azat Miftakhov languishes in a penal colony.
