Abraham Plessner
Abraham Plessner (February 13, 1900 – April 18, 1961) was a Russian mathematician. He was born on February 13, 1900, to a Jewish family in Łódź, which is now in Poland. He studied at secondary school where he was taught in Russian, German, and Polish. He studied at the University of Giessen where he studied under Ludwig Schlesinger and Friedrich Engel (mathematician), Friedrich Engel. He also studied at the University of Göttingen and Berlin. He completed his doctorate from the University of Giessen in 1922. Jointly with Kurt Hensel he edited Leopold Kronecker, Kronecker's collected works. After completing his doctorate, Plessner worked in Marburg where he published a paper containing what is now called Plessner's theorem. It is a theorem concerning the boundary behaviour of functions meromorphic in the unit disk. Plessner submitted his habilitation, the extra post-doctoral qualification needed to lecture at a German university, to the faculty at the University of Giessen. ...

Steklov Institute Of Mathematics
Steklov Institute of Mathematics or Steklov Mathematical Institute (russian: Математический институт имени В.А.Стеклова) is a premier research institute based in Moscow, specialized in mathematics, and a part of the Russian Academy of Sciences. The institute is named after Vladimir Andreevich Steklov, who in 1919 founded the Institute of Physics and Mathematics in Leningrad. In 1934, this institute was split into separate parts for physics and mathematics, and the mathematical part became the Steklov Institute. At the same time, it was moved to Moscow. The first director of the Steklov Institute was Ivan Matveyevich Vinogradov. From 19611964, the institute's director was the notable mathematician Sergei Chernikov. The old building of the Institute in Leningrad became its Department in Leningrad. Today, that department has become a separate institute, called the ''St. Petersburg Department of Steklov Institute of Mathematics of Russian Academy ...

Russian Academy Of Sciences
The Russian Academy of Sciences (RAS; russian: Росси́йская акаде́мия нау́к (РАН) ''Rossíyskaya akadémiya naúk'') consists of the national academy of Russia; a network of scientific research institutes from across the Russian Federation; and additional scientific and social units such as libraries, publishing units, and hospitals. Peter the Great established the Academy (then the St. Petersburg Academy of Sciences) in 1724 with guidance from Gottfried Leibniz. From its establishment, the Academy benefitted from a slate of foreign scholars as professors; the Academy then gained its first clear set of goals from the 1747 Charter. The Academy functioned as a university and research center throughout the mid-18th century until the university was dissolved, leaving research as the main pillar of the institution. The rest of the 18th century continuing on through the 19th century consisted of many published academic works from Academy scholars and a few Ac ...

USSR State Prize
The USSR State Prize (russian: links=no, Государственная премия СССР, Gosudarstvennaya premiya SSSR) was the Soviet Union's state honor. It was established on 9 September 1966. After the dissolution of the Soviet Union, the prize was followed up by the State Prize of the Russian Federation. The State Stalin Prize ( Государственная Сталинская премия, ''Gosudarstvennaya Stalinskaya premiya''), usually called the Stalin Prize, existed from 1941 to 1954, although some sources give a termination date of 1952. It essentially played the same role; therefore upon the establishment of the USSR State Prize, the diplomas and badges of the recipients of Stalin Prize were changed to that of USSR State Prize. In 1944 and 1945, the last two years of the Second World War, the award ceremonies for the Stalin Prize were not held. Instead, in 1946 the ceremony was held twice: in January for the works created in 1943–1944 and in June for the ...

People From Noginsk
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...
