Mikhail Kravchuk
Mykhailo Pylypovych Kravchuk, also Krawtchouk ( uk, Миха́йло Пили́пович Кравчу́к) (September 27, 1892 – March 9, 1942), was a Soviet Ukrainian mathematician and the author of around 180 articles on mathematics. He primarily wrote papers on differential equations and integral equations, studying both their theory and applications. His two-volume monograph on the solution of linear differential and integral equations by the method of moments was translated 1938–1942 by John Vincent Atanasoff who found this work useful in his computer-project ( Atanasoff–Berry computer). His student Klavdiya Latysheva was the first Ukrainian woman to obtain a doctorate in the mathematical and physical sciences (1936). Kravchuk held a mathematics chair at the Kyiv Polytechnic Institute. His course listeners included Sergey Korolev, Arkhip Lyulka, and Vladimir Chelomei, future leading rocket and jet engine designers. Kravchuk was arrested by the Soviet secret police ...

Volyn Governorate
Volhynian Governorate or Volyn Governorate (russian: Волы́нская губе́рния, translit=Volynskaja gubernija, uk, Волинська губернія, translit=Volynska huberniia) was an administrative-territorial unit initially of the Russian Empire, created at the end of 1796 after the Third Partition of Poland from the territory of the short-lived Volhynian Vice-royalty and Wołyń Voivodeship (1569–1795), Wołyń Voivodeship. After the Peace of Riga, part of the governorate became the Wołyń Voivodeship (1921–1939), new Wołyń Voivodeship in the Second Polish Republic, while the other part stayed as a part of the Ukrainian SSR until 1925 when it was abolished on resolution of the All-Ukrainian Central Executive Committee and Counsel of People's Commissars. History Until 1796 the guberniya was administrated as a namestnichestvo (Vice-royalty). It was initially centred in Iziaslav, Ukraine, Iziaslav and was called the Izyaslav namesnichestvo. It was cre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Differential Equations
In mathematics, a differential equation is an equation that relates one or more unknown functions and their derivatives. In applications, the functions generally represent physical quantities, the derivatives represent their rates of change, and the differential equation defines a relationship between the two. Such relations are common; therefore, differential equations play a prominent role in many disciplines including engineering, physics, economics, and biology. Mainly the study of differential equations consists of the study of their solutions (the set of functions that satisfy each equation), and of the properties of their solutions. Only the simplest differential equations are solvable by explicit formulas; however, many properties of solutions of a given differential equation may be determined without computing them exactly. Often when a closed-form expression for the solutions is not available, solutions may be approximated numerically using computers. The theory of d ...

People From Volyn Oblast
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 ...

The Soviet Union,. officially the Union of Soviet Socialist Republics. (USSR),. was a transcontinental country that spanned much of Eurasia from 1922 to 1991. A flagship communist state, it was nominally a federal union of fifteen national republics; in practice, both its government and its economy were highly centralized until its final years. It was a one-party state governed by the Communist Party of the Soviet Union, with the city of Moscow serving as its capital as well as that of its largest and most populous republic: the Russian SFSR. Other major cities included Leningrad (Russian SFSR), Kiev (Ukrainian SSR), Minsk (Byelorussian SSR), Tashkent (Uzbek SSR), Alma-Ata (Kazakh SSR), and Novosibirsk (Russian SFSR). It was the largest country in the world, covering over and spanning eleven time zones.

Eponym
An eponym is a person, a place, or a thing after whom or which someone or something is, or is believed to be, named. The adjectives which are derived from the word eponym include ''eponymous'' and ''eponymic''. Usage of the word The term ''eponym'' functions in multiple related ways, all based on an explicit relationship between two named things. A person, place, or thing named after a particular person share an eponymous relationship. In this way, Elizabeth I of England is the eponym of the Elizabethan era. When Henry Ford is referred to as "the ''eponymous'' founder of the Ford Motor Company", his surname "Ford" serves as the eponym. The term also refers to the title character of a fictional work (such as Rocky Balboa of the Rocky film series, ''Rocky'' film series), as well as to ''self-titled'' works named after their creators (such as the album The Doors (album), ''The Doors'' by the band the Doors). Walt Disney created the eponymous The Walt Disney Company, Walt Disney Com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gulag
The Gulag, an acronym for , , "chief administration of the camps". The original name given to the system of camps controlled by the GPU was the Main Administration of Corrective Labor Camps (, )., name=, group= was the government agency in charge of the Soviet network of forced labour camps which were set up by order of Vladimir Lenin, reaching its peak during Joseph Stalin's rule from the 1930s to the early 1950s. English-language speakers also use the word ''gulag'' in reference to each of the forced-labor camps that existed in the Soviet Union, including the camps that existed in the post-Lenin era. The Gulag is recognized as a major instrument of political repression in the Soviet Union. The camps housed a wide range of convicts, from petty criminals to political prisoners, a large number of whom were convicted by simplified procedures, such as NKVD troikas or other instruments of extrajudicial punishment. In 1918–22, the agency was administered by the Cheka, follow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
