Nikolai Korobov

Nikolai Mikhailovich Korobov (1917 to 2004) was a Soviet mathematician who specialized in number theory and numerical analysis. He was born on 23 November 1917 and died on 25 October 2004. He is best known for his work in analytic number theory, especially in exponential and trigonometric sums. The English Wikipedia infobox for his student Anatoly Karatsuba names Korobov as Karatsuba's doctoral advisor, and Karatsuba went on to develop a p-adic method for estimating trigonometric sums, so the two mathematicians are linked through that subject. The Wikipedia article on Korobov is brief, so this entry records only his field, his best-known area of work, his dates and that advisor link.
