Ivan Matveevich Vinogradov Guide, Meaning , Facts, Information and Description
Ivan Matveevich Vinogradov (September 14, 1891–March 20, 1983) was a Russian mathematician, who was one of the creators of modern analytic number theory, and also the dominant figure in mathematics in the USSR. He was born in the Velikiye Luki district, Pskov Oblast. He graduated from the University of St. Petersburg, where in 1920 became a Professor. From 1934 he was a Director of the Steklov Institute of Mathematics, a position he held for the rest of his life, except for the five-year period (1941–1946) when the institute was directed by Academician Sobolev.In analytic number theory, Vinogradov's method refers to his main problem-solving technique, applied to central questions involving the estimation of exponential sums. With its help, he tackled questions such as the ternary Goldbach problem, and the zero-free region for the Riemann zeta function. His own use of it was inimitable; in terms of later techniques, it is recognised as a prototype of the large sieve method in its application of bilinear forms, and also as an exploitation of combinatorial structure. In some cases his results resisted improvement for decades.
Vinogradov was a Communist Party official, as would be expected at the time of academics highly placed in administrative positions. Given his prominence, it is inescapable to conclude that he must have known of the repressive trends of the Soviet system, as they had an impact on the mathematical community of the USSR, continuing into the Brezhnev era. The best-known of these was the harassment of Jewish refuseniks, actively promoted by the KGB; but there were other aspects, beginning with but not limited to the difficulties placed in the way of talented Jewish students wishing to enter universities to study mathematics. There were further drives against dissidents who were not Jewish (for example those with Orthodox Christian and Slavophile beliefs); promotion of party hacks with inadequate research work; limitation of foreign travel in the cases of the most distinguished academics; and alleged abuse of position to implement plagiarism.
It is not clear, and may never be known in detail, if Vinogradov himself was subject to particular pressure from the KGB to implement and continue such policies (well after the Stalin era). This being said, the evidence drawn from his behaviour and that of his associates, and from his rather overpowering character at the personal level, has led many people to very unfavourable conclusions about his complicity.
