Anatoly Moiseevich Vershik (Russian: Анато́лий Моисе́евич Ве́ршик ; born on 28 December 1933 in Leningrad) is a Soviet and Russian mathematician.
 He is most famous for his joint work with Sergey V. Kerov on representations of infinite symmetric groups and applications to the longest increasing subsequences.
Sofia Vasilyevna Kovalevskaya (Russian: Со́фья Васи́льевна Ковале́вская ), born Sofia Vasilyevna Korvin-Krukovskaya (1850–1891), was a Russian mathematician who made noteworthy contributions to analysis, partial differential equations and mechanics.
 She was the first major Russian female mathematician and a pioneer for women in mathematics around the world.
 She was the first woman appointed to a full professorship in Northern Europe and was also one of the first women to work for a scientific journal as an editor.
 Her sister was the socialist Anne Jaclard.
Leonid Eduardovich Slutsky (Russian: Леонид Эдуардович Слуцкий , also transliterated Leonid Slutskii or Slutskiy; born January 4, 1968) is a member of the State Duma of Russia, a member of the LDPR party.
 In the 6th State Duma, he was the Chairman of the State Duma Committee on the Commonwealth of Independent States, Eurasian Integration and Relations with Compatriots.
 In the 7th State Duma, Slutsky is the Chairman of the Committee on International Affairs.
The Karatsuba algorithm is a fast multiplication algorithm.
 It was discovered by Anatoly Karatsuba in 1960 and published in 1962.
 It reduces the multiplication of two "n"-digit numbers to at most formula_1 single-digit multiplications in general (and exactly formula_2 when "n" is a power of 2).
 It is therefore faster than the classical algorithm, which requires "n" single-digit products.
 For example, the Karatsuba algorithm requires 3 = 59,049 single-digit multiplications to multiply two 1024-digit numbers ("n" = 1024 = 2), whereas the classical algorithm requires (2) = 1,048,576.
The New Chronology is a pseudohistorical theory which argues that the conventional chronology of Middle Eastern and European history is fundamentally flawed, and that events attributed to the civilizations of the Roman Empire, Ancient Greece and Ancient Egypt actually occurred during the Middle Ages, more than a thousand years later.
 The central concepts of the New Chronology are derived from the ideas of Russian scholar Nikolai Morozov (1854–1946), although work by French scholar Jean Hardouin (1646–1729) can be viewed as an earlier predecessor.
 However, the New Chronology is most commonly associated with Russian mathematician Anatoly Fomenko (born 1945), although published works on the subject are actually a collaboration between Fomenko and several other mathematicians.
 The concept is most fully explained in "History: Fiction or Science?"
, originally published in Russian.
The Slutsky equation (or Slutsky identity) in economics, named after Eugen Slutsky, relates changes in Marshallian (uncompensated) demand to changes in Hicksian (compensated) demand, which is known as such since it compensates to maintain a fixed level of utility.
 The equation demonstrates that the change in the demand for a good, caused by a price change, is the result of two effects:
Anatoli (or Anatoly) Nikolaievich Andrianov (Анатолий Николаевич Андрианов, born 21 July 1936) is а Russian mathematician.
Anatoly Timofeevich Fomenko (Russian: Анато́лий Тимофе́евич Фоме́нко ) (born 13 March 1945 in Stalino, USSR) is a Soviet and Russian mathematician, professor at Moscow State University, well known as a topologist, and a member of the Russian Academy of Sciences.
 He is author of a pseudoscientific theory known as New Chronology.
 He is also a member of the Russian Academy of Natural Sciences (1991).
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.
Evgeny "Eugen" Evgenievich Slutsky ( ; ( Евге́ний Евге́ньевич Слу́цкий) 7 April [O.S. 19 April] 1880 – 10 March 1948) was a Russian/Soviet mathematical statistician, economist and political economist.
