Boycott ICM 2022 in Russia

This page was created for mathematicians to protest against hosting the International Congress of Mathematicians in 2022 by Russia. Saint Petersburg was chosen as the next ICM venue at the 2018 General Assembly of the International Mathematical Union in São Paulo.

Collection of signatures stopped on February 26, 2022 as the IMU took the decision to pull the ICM from Russia. Ukrainian mathematicians: Unfortunately, this right decision was not made before the full scale invasion of the Russian troops to our country.

History of this initiative and related actions

Ukrainian group (since July 2021)

Here are some of the reasons to boycott:

Political prisoners [wiki]

In recent years the number of human rights defenders, journalists and scientists in Russian prisons and penal colonies has risen sharply. As for September 2018, the Russian human rights centre Memorial reports there are at least 188 political prisoners or prisoners of conscience. In the Russian Federation political prisoners are often subjected to abuse or torture.

The international mathematical community is gravely concerned about the situation of Azat Miftakhov, a mathematics graduate student at the Moscow State University. Azat was a target of a brutal smear campaign in the pro-government media and spent almost two years in pre-trial detention. On January 18, 2021 he was sentenced to six years imprisonment in a penal colony. We've been monitoring Azat's case and we believe that the charges against him are a pure invention of the Russian authorities. Before the verdict was announced, 47 mathematicians wrote a letter to the Executive Organizing Committee and Local Organizing Committee of the International Congress of Mathematicians, asking them to take an active position on Azat's case and to communicate with the state authorities to free him. Unfortunately, the ICM organizers decided not to act in his support.
Repression of opponents [wiki]

The most widely known critics of Putin's regime who have been assassinated include the journalist and human rights activist Anna Politkovskaya, liberal politician Sergei Yushenkov, human rights activist Natalya Estemirova, journalist and anti-fascist Anastasia Baburova, human rights lawyer Stanislav Markelov, American journalist and chief editor of the Russian edition of Forbes Paul Klebnikov, physicist and liberal politician Boris Nemtsov. To touch the topic of mathematical sciences, the famous inventor of knot invariants Victor Vassiliev was arrested in 2014 during a peaceful protest in support of the defendants in the Bolotnaya Square Case. At the time when this page was created police crushed a peaceful protest and over 400 people were detained in Saint Petersburg. In January-February 2021 thousands were arrested during peaceful protests against jailing the opposition leader Alexey Navalny. Among them there were many math students and faculty, including professor Alexander Kuznetsov, an EMS Prize recipient and an invited speaker at the International Mathematical Congress in Seoul in 2014.
Discrimination of LGBT people [wiki]

In 2013 Russia adopted a federal law which de facto criminalizes LGBT culture. This resulted in numerous arrests of Russian LGBT citizens publicly opposing the law and there has reportedly been a surge of homophobic propaganda, violence and hate crimes using the law as justification. The respective law was adopted in March of 2012 by the governor of St. Petersburg Georgy Poltavchenko, who was a co-chair of the Executive Organizing Committee for the ICM 2022 in 2018-2019.

United Nations Human Rights Council condemns the wave of torture and killings of gay men in Chechnya in 2017. In May 2019 the Human Rights Watch reported a new anti-gay crackdown in Grozny. In July 2019 a prominent human rights, and LGBT rights activist Yelena Grigoryeva was murdered in Saint Petersburg.
Annexation of Crimea [wiki] and ongoing war in Ukraine [wiki]

In February-March 2014 Russian military troops invaded and annexed the Crimean peninsula from Ukraine. The United Nations General Assembly condemns the annexation and calls upon all states and international organizations not to recognize or to imply the recognition of Crimea as Russian territory. Another resolution of UN documents that Russia systematically curtails civil, political and cultural rights of Crimean Tatars. In July 2019 more than 20 Crimean Tatar activists faced unfounded terrorism charges.

International organizations recognize Russian presence in the military conflict in the East of Ukraine. The war started in 2014 after the annexation of Crimea. It has already taken more than 13,000 lives, wounded over 25,000 and made more than 2,000,000 people to flee their homes. Russian military supplied and subsequently recovered the missile launcher that shot down a scheduled passenger flight MH17 from Amsterdam to Kuala Lumpur on 17 July 2014, killing 298 people.

Starting from November 2021 Ukraine is under the constant threat of a full scale military invasion by the Russian troops. Putin’s regime has moved over 100,000 troops to the Ukrainian border. They are equipped with everything from tanks and artillery to ammunition and air power. In February 2022 many countries started to evacuate their diplomats' families and embassy staff from Ukraine. Never since the Second World War was Europe so close to an outbreak of war on such a large scale.

On February 22, 2022 the American Mathematical Society issued a statement in which they are alarmed of the situation in Ukraine and urge the International Mathematical Union not to hold the ICM in Russia in July 2022.
Air strikes in Syria [wiki]

In 2015 Russia joined the Syrian civil war in support of the president Bashar al-Assad, whose army uses against its population such internationally condemned methods as barrel bombs and chemical strikes. Between April and August 2018, Russia conducted at least 13,000 air strikes. As for September 2018, the UK-based Syrian Network for Human Rights reports over 6,000 civilians killed by the Russian Forces, while the total death toll reaches over 200,000.

The aim of the boycott is not to penalize Russian mathematicians for the actions of Russian government or prevent their collaboration with the colleagues abroad. The Congress is co-organized and financed by the Russian government. We believe that by recognizing the Congress in Russia, the mathematical community indirectly lends credibility to Putin's regime.

Still there is threshold of what is acceptable. For me personally, after the war of 2014, setting a foot on russian soil, not to mention participating in government backed and supported event, is simply unimaginable. Understandably, the outlook of Russia-based mathematicians, even those who vocally oppose the regime (see Vassiliev, Vershik etc.) could be different.

Alexander Soifer	University of Colorado, USA	I am grateful to the July 29-30, 2018, General Assembly (GA) of the International Mathematics Union (IMU) for following my urging and deciding to replace the name of Rolf Nevanlinna, a Hitler supporter, on its prize and medal. However, GA erred in granting criminal tyrant Putin a propaganda tool by selecting Russia for hosting ICM-2022. War on Georgia, Annexation of Crimea, War on Ukraine, etc., etc., etc. are the gravest violations of the international law, and must not be rewarded. I do not think that for countries to order their mathematicians not to attend is right. I support the boycott on the individual level, by those who are not only mathematicians, but also human beings of high moral standards.

Well, I am proud of being gay and I am happy not to be alone in this battle anymore. Russian friends and colleagues, this fight is for you!

Nicolas Dirr	Cardiff University	While previous hosts did not have an unblemished human rights record either, the aggressive attempts of the Russian regime to destabilise democracies in other countries, state sponsored murders of its critics, its disregard for internationally recognised borders and the fact that LGBT mathematicians and mathematicians who disagree with the regime and its allies cannot feel safe in Russia make this case different. The event should be transferred to another country.
Anatolij Plichko	Volodymyr Vynnychenko Central Ukrainian State Pedagogical University
Sergey Mozgovoy	Ireland	As of 2021, there are more than 13000 casualties of the war in Ukraine. There are 1.5 million people who fled from the east of Ukraine to other areas of the country and 1 million people who fled to Russia. On the other hand, the authoritarian regime in Russia finds itself in the process of power transfer caused by life constraints of the top officials. This process leads to political turbulence and results in human rights violations (such as imprisonment and tortures) very high even by the standards of that regime. It would be preposterous to expect from mathematicians any signs of empathy for human suffering, especially at the prospect of social networking and other benefits provided by ICM. I respect my colleagues too much to assume that they will not find very good reasons to put their love and devotion to science above some insignificant and momentary political differences. Yet, I suppose, it could be not completely useless to express my own stance on the event.

Mee Seong Im	United States Naval Academy, Annapolis, MD	With the Russia-Ukraine conflict going on with an increasing number of civilian causalities, now is not the time to be hosting ICM2022 in Russia.
Carl Lian	Humboldt-Universität zu Berlin, Germany
Dmitry Gourevitch	Weizmann Institute of Science	As Fred Fung wrote: Show solidarity with the Ukrainian people suffering from the unprovoked war launched by the Russian government. Holding the ICM in Russia will inadvertently indicate the advocation for Putin's regime from the mathematician community.
Kacper Kania	Warsaw University of Technology
Anton Mosunov	University of Waterloo	In view of Russia's aggression towards Ukraine, it is in the best interest of mathematical community to move ICM 2022 out of Russia. St. Petersburg was a city of Euler and Chebyshev. Now it is a city where thousands of Russians protesting against the war get beaten and imprisoned.

Misha Verbitsky	IMPA, Rio de Janeiro, Brasil	I am not sure if I have signed this letter already, because the treatment of political prisoners is a sufficient cause already to cancel the ICM in Russia. However, the current situation with the war in Ukraine leaves us no other choice, and the congress has to be cancelled regardless of this terrible situation with imprisoned and tortured political activists. Current Russia is a state which can be compared to Nazi Germany in too many different aspects. It cast itself out of the civilized society and has no right (or ability) to host the international congress. The congress obviously should be cancelled, there is nothing to discuss here.

Rodrigo Pérez	IUPUI	What is the IMU afraid of? Money spent in the organization? The Calculus of Freedom, the Geometry of Decency are higher order arguments. Do the right thing or be remembered.
