Математические открытия в тюрьме. Даже Ремесло против Путина. Политзаключённый-рецидивист.

Mathematical discoveries in prison. Even Remeslo against Putin. A recidivist political prisoner.

You’re watching news from the weekly rally in front of the Russian Embassy in Lisbon. Today is August 29th, 2:30 PM.

On Aug. 21, the Free Azat support group reported that the French journal "Revue de la filière mathématiques" had published an article by political prisoner Azat Miftakhov, "Chui's Conjecture in a Hilbert Space," in its June-August issue. The problem was given to him by Bernard Randé, a French mathematician and the journal's editor-in-chief. Azat worked on it for about four months in prison, without internet access or academic books.

In 1971, Charles Chui asked how to arrange N identical charges on a circle so that the field inside the circle would be weakest on average. The answer, "uniformly," seems obvious, but it still has not been proved.

Problems like "where to place points to minimize the field or the error" are used in engineering. The directions used in MRI brain scans are chosen on the same principle. And Zolotarev's 1877 extremal problem became, half a century later, Cauer elliptic filters, which separate the communication channel you need from the others in your phone.

On Aug. 27, the 7x7 reported that prosecutors had requested seven months in a strict-regime penal colony for political prisoner Ivan Lyubshin on charges of evading administrative supervision after trying to leave Russia.

In his final statement, which Ivan sent us and plans to read at a court hearing that has been postponed for now, he quotes the Constitution: "The recognition, observance and protection of human rights and freedoms is the duty of the state." He writes that his desire to leave arose back in 2019, "when FSB officers beat and tortured me during my arrest in October," and that he became firmer in that resolve after going through the Russian prison system, which he calls "not correctional at all, but punitive." "Russian courts did not acquit me, but they acquitted those who beat me," he concludes.

Russia is not their property.
