full_context: Document 1: Leonty Magnitsky: Leonty Filippovich Magnitsky (Russian: Леонтий Филиппович Магницкий ), born Telyatin (Russian: Телятин ), (June 9, 1669, Ostashkov – October 19, 1739, Moscow) was a Russian mathematician and educator.

Document 3: Yuri Matiyasevich: Yuri Vladimirovich Matiyasevich, (Russian: Ю́рий Влади́мирович Матиясе́вич ; born March 2, 1947, in Leningrad) is a Russian mathematician and computer scientist. He is best known for his negative solution of Hilbert's tenth problem (Matiyasevich's theorem), which was presented in his doctoral thesis at LOMI (the Leningrad Department of the Steklov Institute of Mathematics).
Document 4: John Napier: John Napier of Merchiston ( ; 1 February, 1550 – 4 April 1617); also signed as Neper, Nepair; nicknamed Marvellous Merchiston) was a Scottish landowner known as a mathematician, physicist, and astronomer. He was the 8th Laird of Merchiston. His Latinized name was Ioannes Neper.
Document 5: Leonid Levin: Leonid Anatolievich Levin ( ; Russian: Леони́д Анато́льевич Ле́вин ; Ukrainian: Леоні́д Анато́лійович Ле́він ; born November 2, 1948) is a Soviet-American computer scientist.
Document 6: Krylov–Bogoliubov averaging method: The Krylov–Bogolyubov averaging method (Krylov–Bogolyubov method of averaging) is a mathematical method for approximate analysis of oscillating processes in non-linear mechanics. The method is based on the averaging principle when the exact differential equation of the motion is replaced by its averaged version. The method is named after Nikolay Krylov and Nikolay Bogoliubov.
Document 7: Nikolay Mitrofanovich Krylov: Nikolay Mitrofanovich Krylov (Russian: Никола́й Митрофа́нович Крыло́в , Ukrainian: Микола Митрофанович Крилов ) (29 November [O.S. 17 November] 1879 – May 11, 1955) was a Russian and Soviet mathematician known for works on interpolation, non-linear mechanics, and numerical methods for solving equations of mathematical physics.
Document 8: Nicolai V. Krylov: Nicolai Vladimirovich Krylov (Russian: Никола́й Влади́мирович Крыло́в ; born 5 June 1941) is a Russian mathematician specializing in partial differential equations, particularly stochastic partial differential equations and diffusion processes. Krylov studied at Lomonosov University, where he in 1966 under E. B. Dynkin attained a doctoral candidate title (similar to a PhD) and in 1973 a Russian doctoral degree (somewhat more prestigious than a PhD). He taught from 1966 to 1990 at the Lomonosov University and is since 1990 a professor at the University of Minnesota. At the beginning of his career (starting from 1963) he, in collaboration with Dynkin, worked on nonlinear stochastic control theory, making advances in the study of convex, nonlinear partial equations of 2nd order ("i.e." Bellman equations), which were examined with stochastic methods. This led to the Evans-Krylov theory, for which he received with Lawrence C. Evans in 2004 the Leroy P. Steele Prize of the American Mathematical Society (for work done simultaneously and independently by both Krylov and Evans). They proved the second order differentiability (Hölder continuity of the second derivative) of the solutions of convex, completely nonlinear, second order elliptical partial differential equations and thus the existence of "classical solutions" (Theorem of Evans-Krylov). He was in 1978 at Helsinki and in 1986 at Berkeley an Invited Speaker for the ICM. He received the Humboldt Research Award in 2001. In 1993 he was elected a member of the American Academy of Arts and Sciences (1993). He should not be confused with the mathematician Nikolay M. Krylov.
Document 9: Lev Pontryagin: Lev Semyonovich Pontryagin (Russian: Лев Семёнович Понтрягин , also written Pontriagin or Pontrjagin) (3 September 1908 – 3 May 1988) was a Soviet mathematician. He was born in Moscow and lost his eyesight due to a primus stove explosion when he was 14. Despite his blindness he was able to become one of the greatest mathematicians of the 20th century, partially with the help of his mother Tatyana Andreevna who read mathematical books and papers (notably those of Heinz Hopf, J. H. C. Whitehead, and Hassler Whitney) to him. He made major discoveries in a number of fields of mathematics, including algebraic topology and differential topology.
Document 10: Mikhail Kravchuk: Mykhailo Pylypovych Kravchuk, also Krawtchouk (Ukrainian: Миха́йло Пили́пович Кравчу́к ) (September 27, 1892 – March 9, 1942), was a Soviet Ukrainian mathematician who, despite his early death, was the author of around 180 articles on mathematics.
Document 11: Nikolay Sergeyevich Krylov: Nikolay Sergeevich Krylov (Russian: Никола́й Серге́евич Крыло́в }; 10 August 1917 – 21 June 1947) was a Russian theoretical physicist known for his work on the foundations of statistical physics. He showed that a sufficient condition for a dynamical system to relax to equilibrium is for it to be mixing.
Document 12: Krylov–Bogolyubov theorem: In mathematics, the Krylov–Bogolyubov theorem (also known as the existence of invariant measures theorem) may refer to either of the two related fundamental theorems within the theory of dynamical systems. The theorems guarantee the existence of invariant measures for certain "nice" maps defined on "nice" spaces and were named after Russian-Ukrainian mathematicians and theoretical physicists Nikolay Krylov and Nikolay Bogolyubov who proved the theorems.
Document 13: Nicolai Reshetikhin: Nicolai Yuryevich Reshetikhin (Russian: Николай Юрьевич Решетихин , born October 10, 1958 in Leningrad, Soviet Union) is a mathematical physicist, currently a professor of mathematics at the University of California, Berkeley and a professor of mathematical physics at the University of Amsterdam. His research is in the fields of low-dimensional topology, representation theory, and quantum groups. His major contributions are in the theory of quantum integrable systems, in representation theory of quantum groups
Document 14: Mykola Leontovych: Leontovych was born and raised in the Podolia Governorate of the Russian Empire (present-day Ukraine). He was educated as a priest in the Kamianets-Podilskyi Theological Seminary and later furthered his musical education at the Saint Petersburg Court Capella and private lessons with Boleslav Yavorsky. With the independence of the Ukrainian state in the 1917 revolution, Leontovych moved to Kiev where he worked at the Kiev Conservatory and the Mykola Lysenko Institute of Music and Drama. He is recognized for composing "Shchedryk" in 1904 (which premiered in 1916), known to the English-speaking world as "Carol of the Bells" or "Ring, Christmas Bells". He is known as a martyr in the Eastern Orthodox Ukrainian Church, where he is also remembered for his liturgy, the first liturgy composed in the vernacular, specifically in the modern Ukrainian language. He was assassinated by a Soviet agent in 1921.
Document 15: Andrey Kolmogorov: Andrey Nikolaevich Kolmogorov (Russian: Андрей Николаевич Колмогоров ; ] , 25 April 1903 – 20 October 1987) was a 20th-century Soviet mathematician who made significant contributions to the mathematics of probability theory, topology, intuitionistic logic, turbulence, classical mechanics, algorithmic information theory and computational complexity.
