Yuri Vladimirovich Linnik (Russian: Ю́рий Влади́мирович Ли́нник; January 8, 1915 – June 30, 1972) was a Soviet mathematician active in number theory, probability theory and mathematical statistics.
Biography
[edit]Linnik was born in Bila Tserkva, in present-day Ukraine. He went to Saint Petersburg University where his supervisor was Vladimir Tartakovsky, and later worked at that university and the Steklov Institute. He was a member of the Academy of Sciences of the Soviet Union, as was his father, Vladimir Pavlovich Linnik. He was awarded both Stalin and Lenin Prizes. He died in Leningrad.[1]
Work in number theory
[edit]- Linnik's theorem in analytic number theory
- The dispersion method (which allowed him to solve the Titchmarsh problem).[2]
- The large sieve (which turned out to be extremely influential).
- An elementary proof of the Hilbert-Waring theorem; see also Schnirelmann density.
- The Linnik ergodic method, see Linnik (1968), which allowed him to study the distribution properties of the representations of integers by integral ternary quadratic forms.[3]
Work in probability theory and statistics
[edit]Infinitely divisible distributions
[edit]Linnik obtained numerous results concerning infinitely divisible distributions.[4] In particular, he proved the following generalisation of Cramér's theorem: any divisor of a convolution of Gaussian and Poisson random variables is also a convolution of Gaussian and Poisson.
He has also coauthored the book Linnik & Ostrovskii (1977) on the arithmetics of infinitely divisible distributions.
Central limit theorem
[edit]- Linnik zones (zones of asymptotic normality)
- Information-theoretic proof of the central limit theorem
