Question: Which mathematician was born first,  Ivan Fesenko or Dmitri Anosov?

full_context: Document 1: Victor Kolyvagin: Victor Alexandrovich Kolyvagin (Russian: Ви́ктор Алекса́ндрович Колыва́гин ) is a Russian mathematician who wrote a series of papers on Euler systems, leading to breakthroughs on the Birch and Swinnerton-Dyer conjecture, and Iwasawa's conjecture for cyclotomic fields. His work also influenced Andrew Wiles's work on Fermat's Last Theorem.
Document 2: Dmitri Egorov: Dmitri Fyodorovich Egorov (Russian: Дми́трий Фёдорович Его́ров ; December 22, 1869 – September 10, 1931) was a Russian and Soviet mathematician known for significant contributions to the areas of differential geometry and mathematical analysis. He was President of the Moscow Mathematical Society (1923 — 1930).
Document 3: Aleksandr Andronov: Aleksandr Aleksandrovich Andronov (Russian: Алекса́ндр Алекса́ндрович Андро́нов ; April 11 [O.S. March 29] 1901 , Moscow – October 31, 1952, Gorky) was a Soviet physicist and member of the Soviet Academy of Sciences (1946). He worked extensively on the theory of stability of dynamical systems, introducing (together with Lev Pontryagin) the notion of structural stability. In that context, he also contributed to the mathematical theory of self-oscillation (a term that he coined) by establishing a link between the generation of oscillations and the theory of Lyapunov stability. He developed the comprehensive theory of self-oscillations by linking it with the qualitative theory of differential equations, topology, and with the general theory of stability of motion. The crater Andronov on the Moon is named after him.
Document 4: Ivan Ivanov (mathematician): Ivan Ivanovich Ivanov (Russian: Иван Иванович Иванов ; 11 August 1862 – 17 December 1939) was a Russian-Soviet mathematician who worked in the field of number theory. Together with Georgy Voronoy he continued Pafnuty Chebyshev's work on the subject.
Document 5: 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 6: Fesenko group: In mathematics, Fesenko groups are certain subgroups of the wild automorphism groups of local fields of positive characteristic (i.e. the Nottingham group), studied by Ivan Fesenko ().
Document 7: Ivan Vinogradov: Ivan Matveevich Vinogradov {'1': ", '2': ", '3': 'ForMemRS', '4': "} (Russian: Ива́н Матве́евич Виногра́дов ; ] ; 14 September 1891 – 20 March 1983) (not to be confused with Askold Ivanovich Vinogradov of the Bombieri-Vinogradov theorem) was a Soviet mathematician, who was one of the creators of modern analytic number theory, and also a dominant figure in mathematics in the USSR. He was born in the Velikiye Luki district, Pskov Oblast. He graduated from the University of St. Petersburg, where in 1920 he became a Professor. From 1934 he was a Director of the Steklov Institute of Mathematics, a position he held for the rest of his life, except for the five-year period (1941–1946) when the institute was directed by Academician Sergei Sobolev. In 1941 he was awarded the Stalin Prize. In 1951 he became a foreign member of the Polish Academy of Sciences and Letters in Kraków.
Document 8: Vladimir Voevodsky: Vladimir Alexandrovich Voevodsky ( ; Russian: Влади́мир Алекса́ндрович Воево́дский , 4 June 1966 - 30 September 2017) was a Russian mathematician. His work in developing a homotopy theory for algebraic varieties and formulating motivic cohomology led to the award of a Fields Medal in 2002. He is also known for the proof of the Milnor conjecture and motivic Bloch-Kato conjectures and for the univalent foundations of mathematics and homotopy type theory.
Document 9: Oseledets theorem: In mathematics, the multiplicative ergodic theorem, or Oseledets theorem provides the theoretical background for computation of Lyapunov exponents of a nonlinear dynamical system. It was proved by Valery Oseledets (also spelled "Oseledec") in 1965 and reported at the International Mathematical Congress in Moscow in 1966. A conceptually different proof of the multiplicative ergodic theorem was found by M. S. Raghunathan. The theorem has been extended to semisimple Lie groups by V. A. Kaimanovich and further generalized in the works of David Ruelle, Grigory Margulis, Anders Karlsson, and François Ledrappier.
Document 10: 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 11: Serhiy Fesenko: Sergey Fesenko Jr. (also spelled as Sergiy or Serhiy, born June 5, 1982) is a long-distance freestyle swimmer from Ukraine. He competed in the 2000 Olympic Games in Sydney, Australia, 2004 Olympic Games in Athens, Greece and qualified to represent his country at the 2008 Olympic Games in Beijing, China. As a student at Indiana University, Fesenko was Big Ten swimmer of the week twice and NCAA swimmer of the week once in the 2005–2006 collegiate season. His father, Sergey Fesenko, Sr., won the gold medal in the 200m butterfly at the 1980 Olympic Games in Moscow.
Document 12: 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 13: Dmitri Anosov: Dmitri Victorovich Anosov (Russian: Дми́трий Ви́кторович Ано́сов ; November 30, 1936 – August 5, 2014) was a Soviet and Russian mathematician, known for his contributions to dynamical systems theory.
Document 14: Leonid Bunimovich: Leonid Bunimovich is a Soviet and American mathematician, who specializes in dynamical systems. He is known for discovery of a fundamental mechanism of chaos (hyperbolicity) in Dynamical systems, which is called mechanism of defocusing. The most famous class of chaotic dynamical systems of this type Dynamical billiards are focusing chaotic billiards (e.g., the "Bunimovich stadium","Bunimovich flowers", etc.). More recently he introduced so called Bunimovich mushrooms, which are visual examples of billiards with mixed regular and chaotic dynamics. In many labs over the world were built experimental devices in the form of various Bunimovich billiards. He received bachelor's degree in 1967 and PhD in 1973 from the University of Moscow. His thesis adviser was Yakov G. Sinai. In 1986 he was awarded Doctor of Sciences degree in "Theoretical and Mathematical Physics".
Document 15: Ivan Fesenko: Ivan Fesenko (Russian: Иван Борисович Фесенко ; born 1962) is a mathematician working in number theory and other areas of modern mathematics.
ground_truth: Dmitri Victorovich Anosov
