Mikhail Leonidovich Lozinsky (Russian: Михаил Леонидович Лозинский, 20 July 1886 – 31 January 1955) is deemed to be the most accomplished Russian translator of the 20th century.
 "In the difficult and noble art of translation," said Anna Akhmatova, "Lozinsky was for the twentieth century what Zhukovsky was for the nineteenth."
 Lozinsky's granddaughters include writers Tatyana Tolstaya and Natalia Tolstaya.
Open Problems in Mathematics is a book, edited by John Forbes Nash Jr. and Michael Th.
 Rassias, published in 2016 by Springer ().
 The book consists of seventeen expository articles, written by outstanding researchers, on some of the central open problems in the field of mathematics.
 The book also features an Introduction on "John Nash: Theorems and Ideas", by Mikhail Leonidovich Gromov.
 According to the editors’ Preface, each article is devoted to one open problem or a “constellation of related problems”.
Boris (Boaz) Avraamovich Trakhtenbrot (Russian: Борис Авраамович Трахтенброт ; 19 February 1921 – 19 September 2016), or Boaz (Boris) Trakhtenbrot (Hebrew: בועז טרכטנברוט‎ ‎ ) was an Israeli and Russian mathematician in mathematical logic, algorithms, theory of computation, and cybernetics.
 Trakhtenbrot was born in Brichevo, northern Bessarabia.
 He worked at Akademgorodok, Novosibirsk during the 1960s and 1970s.
Richard Lawrence Bishop (born 1932) is an American mathematician, a professor emeritus of mathematics at the University of Illinois at Urbana–Champaign.
 The Bishop–Gromov inequality in Riemannian geometry is named after him (with Mikhail Gromov).
Mikhail Leonidovich Slonimsky (Russian: Михаи́л Леони́дович Слони́мский ; 1 August [O.S. 20 July] 1897 – 8 October 1972) was a Soviet writer, member of the Serapion Brothers group.
In mathematics, the Gromov product is a concept in the theory of metric spaces named after the mathematician Mikhail Gromov.
 The Gromov product can also be used to define "δ"-hyperbolic metric spaces in the sense of Gromov.
In logic, finite model theory, and computability theory, Trakhtenbrot's theorem (due to Boris Trakhtenbrot) states that the problem of validity in first-order logic on the class of all finite models is undecidable.
 In fact, the class of valid sentences over finite models is not recursively enumerable (though it is co-recursively enumerable).
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.
The non-squeezing theorem, also called "Gromov's non-squeezing theorem", is one of the most important theorems in symplectic geometry.
 It was first proven in 1985 by Mikhail Gromov.
Mikhail Leonidovich Bogdanov (born 2 March 1952 in Moscow) is a Russian diplomat.
