Jailed Russian mathematician Azat Miftakhov publishes paper solving Chui’s Conjecture in French journal
The French mathematics journal Revue de la filière mathématique has published an article by Russian political prisoner Azat Miftakhov, “La conjecture de Chui dans un cadre hilbertien” (“Chui’s Conjecture in a Hilbert Space”).
According to his support group's Telegram channel, jailed Russian mathematician Azat Miftakhov has published a paper titled "La conjecture de Chui dans un cadre hilbertien" in the French mathematics journal Revue de la filière mathématique. Miftakhov solved the problem of Chui’s Conjecture while detained in a prison in Dimitrovgrad.
French mathematician Bernard Randé helped secure the article's publication. This marks the third paper Miftakhov has published abroad since his arrest in February 2019. He was initially sentenced for preparing an attack on the office of the United Russia party, and later convicted under a statute banning the justification of terrorism.
Miftakhov has been held at the "Polar Owl" penal colony in Kharp, Yamalo-Nenets Autonomous District since April 2026. Alexey Navalny was killed in February 2024 at a different penal colony in Kharp, "Polar Wolf." The journal Revue de la filière mathématique was established in 1890 and published quarterly.
