Sergei Chernikov
Sergei Nikolaevich Chernikov (11 May 1912 – 23 January 1987; russian: Сергей Николаевич Черников) was a Russian mathematician who contributed significantly to the development of infinite group theory and linear inequalities. Biography Chernikov was born on 11 May 1912 in Sergiyev Posad, in Moscow Oblast, Russia, to Nikolai Nikolaevich, a priest, and Anna Alekseevna, a housewife. After graduating from secondary school, he worked as a labourer, as a driver, as a book-keeper and as an accountant. Until November 1931 he taught mathematics in a school for workers. From 1930 he was an external student of the Pedagogic Institute of Saratov State University, where he graduated in 1933. He began graduate studies at the Ural Industrial Institute under the outside tutelage of Alexandr G. Kurosh (of the University of Moscow). A remarkable student, Chernikov was made head of the Ural Mathematics department (1939–1946) immediately after earning his PhD in 193 ...

Sergiyev Posad
Sergiyev Posad ( rus, Се́ргиев Поса́д, p=ˈsʲɛrgʲɪ(j)ɪf pɐˈsat) is a city and the administrative center of Sergiyevo-Posadsky District in Moscow Oblast, Russia. Population: It was previously known as ''Sergiyev Posad'' (until 1919), ''Sergiyev'' (until 1930), ''Zagorsk'' (until 1991). History Sergiyev Posad grew in the 15th century around one of the greatest of Russian monasteries, the Trinity Lavra established by St. Sergius of Radonezh, still () one of the largest monasteries in Russia. Town status was granted to Sergiyev Posad in 1742. The town's name, alluding to St. Sergius, has strong religious connotations. Soviet authorities changed it first to just Sergiyev in 1919, and then to Zagorsk in 1930, in memory of the revolutionary Vladimir Zagorsky. Sergiyev Posad was penetrated by Germany in 1941. The original name was restored in 1991. Administrative and municipal status Within the framework of administrative divisions, Sergiyev Posad s ...

People From Sergiyev Posad
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 ...

1912 Births
Year 191 ( CXCI) was a common year starting on Friday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Apronianus and Bradua (or, less frequently, year 944 '' Ab urbe condita''). The denomination 191 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Nilpotent Group
In mathematics, specifically group theory, a nilpotent group ''G'' is a group that has an upper central series that terminates with ''G''. Equivalently, its central series is of finite length or its lower central series terminates with . Intuitively, a nilpotent group is a group that is "almost abelian". This idea is motivated by the fact that nilpotent groups are solvable, and for finite nilpotent groups, two elements having relatively prime orders must commute. It is also true that finite nilpotent groups are supersolvable. The concept is credited to work in the 1930s by Russian mathematician Sergei Chernikov. Nilpotent groups arise in Galois theory, as well as in the classification of groups. They also appear prominently in the classification of Lie groups. Analogous terms are used for Lie algebras (using the Lie bracket) including nilpotent, lower central series, and upper central series. Definition The definition uses the idea of a central series for a group. The fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Locally Finite Group
In mathematics, in the field of group theory, a locally finite group is a type of group that can be studied in ways analogous to a finite group. Sylow subgroups, Carter subgroups, and abelian subgroups of locally finite groups have been studied. The concept is credited to work in the 1930s by Russian mathematician Sergei Chernikov. Definition and first consequences A locally finite group is a group for which every finitely generated subgroup is finite. Since the cyclic subgroups of a locally finite group are finitely generated hence finite, every element has finite order, and so the group is periodic. Examples and non-examples Examples: * Every finite group is locally finite * Every infinite direct sum of finite groups is locally finite (Although the direct product may not be.) * Omega-categorical groups * The Prüfer groups are locally finite abelian groups * Every Hamiltonian group is locally finite * Every periodic solvable group is locally finite . * Every subgroup of ...

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 ...

Perm State University
Perm State University (now Perm State National Research University; russian: Пермский университет, Пермский государственный университет, , romanised: , ) or PSU, PSNRU (russian: ПГУ, , romanised: , ), is located in the city of Perm, Perm Krai, Russia. Founded in 1916, it claims to be one of the oldest universities in the Ural and eastern territories of Russia. Its current rector is Dmitriy Krasilnikov. History Perm State University was founded on 14 October 1916. Its origins lie in the opening of a branch of St. Petersburg University in the city of Perm. This decision of the Russian government was in tune with the strategy of the cultural and geopolitical development of the Urals economic region. The idea of a center of higher education in the Urals was supported by D.I. Mendeleev, A.S.Popov, D.N.Mamin-Sibiryak, and other public figures. A mass shooting occurred at the university on 20 September 2021, by a law st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
