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

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

  • 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

Infinitely divisible distributions

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) on the arithmetics of infinitely divisible distributions.
