T-invariant presents the latest regular report Chronicle of the Persecution of Scientists No. 37, dated September 30, 2026. The Russian government has approved the Concept for the Development of Mathematical Sciences through 2036. One of the key issues the Concept highlights is restricted access to international scientific and technical information. Below, we briefly comment on what access to foreign journals looks like today and what is at stake.
Update, October 5, 2026: Our full commentary on the Concept for the Development of Mathematical Sciences through 2036 is available here.
In this Chronicle, we will say a few words about how this “restricted access” has less to do with science than with the repressive policies of a state that interferes with scientists’ normal work.
Mathematics has always been — and still is — one indivisible whole. There is no such thing as “sovereign” or “national” mathematics. Any attempt at isolation inevitably leads to rapid decline. Mathematicians in Russia need to read the work of mathematicians in America and Europe. But the reverse is also true: even during the Cold War, Western mathematicians tried to keep up their collaboration with Soviet colleagues, and the major Soviet mathematical journals were translated into English.
In the internet age, one would think nothing could stop scientists from sharing their knowledge and results. Yet since the start of the full-scale war in Ukraine in 2022, the situation has grown increasingly difficult. The dialogue is breaking down.
As T-invariant reported, starting January 1, 2027, Pleiades Publishing, which works with Springer Nature, will stop producing English-language versions of 108 Russian academic journals. According to the Pleiades catalog, these include Doklady Mathematics, Mathematical Notes, and Proceedings of the Steklov Institute of Mathematics. It is unclear who will translate these journals or whether they will remain indexed in international databases. Meanwhile, the English versions of Sbornik: Mathematics, Izvestiya: Mathematics, and Russian Mathematical Surveys, published jointly with the London Mathematical Society, were suspended back in 2022.
Many Russian mathematicians are fluent in English and could, in principle, submit their papers directly to international journals. But the sanctions policies of many publishers, combined with the policies of the Russian authorities, make this difficult and even risky (T-invariant examined this situation in detail in “Black Mark in the ‘White List’”).
T-invariant has written about the “Yaroslavl admins,” who were fined in cases brought by the FSB. Here is a quick recap. Website administrators at as many as four universities in Yaroslavl were fined. The cases were initiated by the FSB Directorate for the Yaroslavl Region. The university employees were accused of hosting on their websites materials and dissertations in which FSB officers had found references to publications linked to “undesirable” organizations [foreign and international organizations banned in Russia; any involvement with them is punishable by law — T-invariant]. The case against Yaroslav Renin centered on a dissertation that cited Yale University, which has been declared “undesirable.” The Prosecutor General’s Office has also declared Stanford University, the University of California, Berkeley, and Tufts University undesirable. All of these universities have strong math departments. Some very serious mathematicians work there. And they publish papers.
Suppose the calls in the Concept for the Development of Mathematical Sciences through 2036 are heeded, and Russian scientists gain official access to the work of their colleagues at Yale. What are they supposed to do with that access? They won’t even be able to cite a single paper.
The situation is deeply alarming for Russian mathematicians: Russian journals and papers are becoming inaccessible in the West, while citing Western ones is becoming extremely risky. Say you cite a perfectly permissible journal today — one affiliated with Princeton University, for instance — and tomorrow the Prosecutor General’s Office declares Princeton “undesirable.” Your paper, or even your dissertation, will then have to be either rewritten or simply thrown in the trash. Why take that risk? Better to play it safe and not cite these potentially dangerous Western journals — or, better still, not read them at all.
New Cards
September 10, 2026. Tatyana Kudryavtseva, a professor at Herzen State Pedagogical University of Russia, was forced to resign after 30 years at the university over old Instagram posts containing “extremist symbols” [e.g., a photo of graffiti depicting Alexei Navalny — T-invariant]. She announced this on her page on the Russian social network VKontakte.
September 4, 2026. Russia’s Ministry of Justice added bioinformatics professor Tatiana Tatarinova to its register of foreign agents. According to the ministry, Tatarinova spread false information about decisions by the Russian authorities and about Russia’s electoral system, and also collaborated with foreign agents and distributed their materials, RBC reports.
July 31, 2026. Igor Zaitsev was detained on criminal charges of financing extremist activity, according to the Interior Ministry’s Main Directorate and the FSB Directorate for St. Petersburg and the Leningrad Region. The scientist faces up to eight years in prison, RBC reports.
Faculty of Liberal Arts and Sciences (FLAS)
August 29, 2026. The Faculty of Liberal Arts and Sciences in Montenegro has been added to the list of undesirable organizations on the Ministry of Justice website, T-invariant reports.
Updates
September 16, 2026. The Supreme Court of the Komi Republic [a region in northwestern Russia — T-invariant] sentenced Nikolai Zyuzev to seven years in a strict-regime penal colony in a case over developing a “project directed against the sovereignty and territorial integrity of the Russian Federation,” Mediazona reports. Zyuzev allegedly received more than €2 million from 12 organizations, including Germany’s Hanns Seidel Foundation and the German Council on Foreign Relations. “Zyuzev fully admitted his guilt in the crime he was charged with and exposed the other individuals involved,” the FSB press release states. FSB officials claim that Zyuzev was convicted of high treason (Article 275 of the Russian Criminal Code). Yet a year ago, he was detained and sent to a pretrial detention center on charges of confidential cooperation with foreigners (Article 275.1 of the Criminal Code).
September 15, 2026. Moscow’s Zyuzinsky District Court sentenced Pavel Syutkin to six years in a general-regime penal colony for spreading military “fakes” [i.e., “knowingly false information” about the Russian army — T-invariant], a Mediazona correspondent in the courtroom reports. The trial was held behind closed doors. Prosecutors had sought an eight-year sentence.
September 4, 2026. Moscow’s Gagarinsky District Court fined Ekaterina Zhuravskaya in an administrative case over ties to an “undesirable” organization, Mediazona reports. The case was brought over links she posted on X (formerly Twitter) to materials from Deutsche Welle, The Insider, Radio Liberty, TV Rain, and Meduza — seven posts in total, published between December 2024 and May 2026.
September 3, 2026. Misha Verbitsky was dismissed from IMPA, the Brazilian institute where he worked, over his LiveJournal posts, T-invariant reports. The editors have obtained the letter notifying him of the decision. It does not specify which posts led to his dismissal.
August 19, 2026. The Interior Ministry put Vasilina Orlova on its wanted list, Mediazona reports.
Her entry in the Interior Ministry’s database states that she is wanted under a criminal statute. It had not previously been reported that a criminal case had been opened against her. In 2024, Orlova was fined on an administrative charge of participating in the activities of an “undesirable” organization. The charge stemmed from the anthropologist’s online participation in the Free Nations of Post-Russia Forum, held in Tokyo in 2023.
