Person: Chebotaryov, Nikolai Grigorievich
Nikolai Chebotaryov proved his density theorem generalising Dirichlet's theorem on primes in an arithmetical progression.
Mathematical Profile (Excerpt):
 Nikolai entered the University of Kiev in 1912 where he became a student of Grave.
 In this same year, 1922, Nikolai was to prove the theorem for which he is best known, the density theorem, which had been conjectured by Frobenius in a paper written in 1880 but only published in 1896.
 It was an unhappy situation and Chebotaryov resigned after a few months.
 Chebotaryov received his doctorate from the Ukrainian Academy of Sciences with a doctoral thesis based on his 1922 result, the density theorem.
 Chebotaryov worked on the algebra of polynomials, in particular examining the distribution of the zeros.
Born 15 June 1894, KamianetsPodilskyi, Ukraine. Died 2 July 1947, Moscow, USSR.
