Question: What occupation did Eugene Dynkin and Anatoly Maltsev both have in common?

full_context: Document 1: Evgenii Georgievich D'yakonov: D'yakonov was a Ph.D. student of Sergei Sobolev. He worked at the Moscow State University. He authored over hundred papers and several books. D'yakonov was recognized for his pioneering work in the 60s–80s on efficient spectrally equivalent preconditioning for linear systems and eigenvalue problems. In the last decade, strengthened Sobolev spaces became D'yakonov's main topic of research, e.g., (D'yakonov, 2004).
Document 2: Eugene Dynkin: Eugene Borisovich Dynkin (Russian: Евге́ний Бори́сович Ды́нкин ; 11 May 1924 – 14 November 2014) was a Soviet and American mathematician. He has made contributions to the fields of probability and algebra, especially semisimple Lie groups, Lie algebras, and Markov processes. The Dynkin diagram, the Dynkin system, and Dynkin's lemma are named after him.
Document 3: 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.
Document 4: Doob–Dynkin lemma: In probability theory, the Doob–Dynkin lemma, named after Joseph L. Doob and Eugene Dynkin, characterizes the situation when one random variable is a function of another by the inclusion of the formula_1-algebras generated by the random variables. The usual statement of the lemma is formulated in terms of one random variable being measurable with respect to the formula_1-algebra generated by the other.
Document 5: Dynkin diagram: In the mathematical field of Lie theory, a Dynkin diagram, named for Eugene Dynkin, is a type of graph with some edges doubled or tripled (drawn as a double or triple line). The multiple edges are, within certain constraints, directed.
Document 6: Dynkin's formula: In mathematics — specifically, in stochastic analysis — Dynkin's formula is a theorem giving the expected value of any suitably smooth statistic of an Itō diffusion at a stopping time. It may be seen as a stochastic generalization of the (second) fundamental theorem of calculus. It is named after the Russian mathematician Eugene Dynkin.
Document 7: 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 8: Anatoly Maltsev: Anatoly Ivanovich Maltsev (also: Malcev, Mal'cev; Russian: Анато́лий Ива́нович Ма́льцев; 27 November N.S./14 November O.S. 1909, Moscow Governorate – 7 June 1967, Novosibirsk) was born in Misheronsky, near Moscow, and died in Novosibirsk, USSR. He was a mathematician noted for his work on the decidability of various algebraic groups. Malcev algebras (generalisations of Lie algebras) are named after him.
Document 9: Efim Zelmanov: Efim Isaakovich Zelmanov (Russian: Ефи́м Исаа́кович Зе́льманов ; born 7 September 1955 in Khabarovsk) is a Russian-American mathematician, known for his work on combinatorial problems in nonassociative algebra and group theory, including his solution of the restricted Burnside problem. He was awarded a Fields Medal at the International Congress of Mathematicians in Zürich in 1994.
Document 10: 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 11: Anatoly Karatsuba: Anatoly Alexeevitch Karatsuba (Russian: Анато́лий Алексе́евич Карацу́ба ; Grozny, Soviet Union, January 31, 1937 – Moscow, Russia, September 28, 2008) was a Russian mathematician working in the field of analytic number theory, "p"-adic numbers and Dirichlet series.
Document 12: Mikhail Leonidovich Gromov: Mikhail Leonidovich Gromov (also Mikhael Gromov, Michael Gromov or Mischa Gromov; Russian: Михаи́л Леони́дович Гро́мов ; born 23 December 1943), is a French-Russian mathematician known for work in geometry, analysis and group theory. He is a permanent member of IHÉS in France and a Professor of Mathematics at New York University.
Document 13: Vladimir Maltsev: Vladimir Maltsev (born 20 April 1974, Makeyevka, Donetsk region) is the People's Deputy of Ukraine, member of the Party of Regions (since November 2007), a member of the Committee on Justice (December 2007).
Document 14: Dynkin system: A Dynkin system, named after Eugene Dynkin, is a collection of subsets of another universal set formula_1 satisfying a set of axioms weaker than those of σ-algebra. Dynkin systems are sometimes referred to as λ-systems (Dynkin himself used this term) or d-system. These set families have applications in measure theory and probability.
Document 15: Eugene Maltsev: Eugene Demjanovich Maltsev (Russian: Евгений Демьянович Мальцев ; August 9, 1929, Ryazan Oblast, USSR — December 24, 2003, Saint Petersburg, Russia) was a Soviet Russian painter, People's Artist of the Russian Federation, a member of the Saint Petersburg Union of Artists (before 1992 — the Leningrad Union of the Soviet Artists), who lived and worked in Leningrad. In 1990-1997 Eugene Maltsev was a head of the Saint Petersburg Union of Artists, in 1989-1991 was elected a People's Deputies of the Soviet Union from the USSR Union of Artists. Maltsev regarded as one of representatives of the Leningrad school of painting, most famous for his portrait and historical paintings.
