Dmitrii Menshov

Dmitrii Evgenevich Menshov, also spelled Menchoff, Menšov, Menchov, (Russian: Дмитрий Евгеньевич Меньшов; 18 April 1892 – 25 November 1988) was a Russian mathematician known for his contributions to the theory of trigonometric series.
Biography

He was a student of Nikolai Luzin, and the co-advisor of Sergey Stechkin. He received USSR State Prize in 1951. He was elected a corresponding member of the Russian Academy of Sciences in 1953.

His construction of a Fourier series with non-zero coefficients which converges to zero almost everywhere gave rise to the theory of Menshov sets.

He proved the Rademacher–Menchov theorem, the Looman–Menchoff theorem, and the Lusin–Menchoff theorem.
