Vladimir Ivanovich Narbut (Russian: Владимир Иванович Нарбут ; Ukrainian: Володи́мир Іва́нович На́рбут ) (1888–1938) - Russian poet of Ukrainian descent, and member of the Acmeist group, brother of Ukrainian artist and graphic designer Georgy Narbut.

 Together with Georgy Voronoy he continued Pafnuty Chebyshev's work on the subject.
In mathematics, a Voronoi formula is an equality involving Fourier coefficients of automorphic forms, with the coefficients twisted by additive characters on either side.
 It can be regarded as a Poisson summation formula for non-abelian groups.
 The Voronoi (summation) formula for GL(2) has long been a standard tool for studying analytic properties of automorphic forms and their "L"-functions.
 There have been numerous results coming out the Voronoi formula on GL(2).
 The concept is named after Georgy Voronoy.
The Fyodorov–Shpagin Model 1922 was an experimental twin barrel machine gun of Russian origin.
 It was designed by Vladimir Fyodorov and Georgy Shpagin and was chambered in 6.5×51mm Fyodorov.

 He worked as the artistic director of the Moscow PO from 1942 to 1949.
 He was made a People’s Artist of the RSFSR and of the Kirghiz SSR.
Vladimir Berkovich is a mathematician at the Weizmann Institute of Science who introduced Berkovich spaces. His Ph.D. advisor was Yuri I. Manin.
 Berkovich was a visiting scholar at the Institute for Advanced Study in 1991-92 and again in the summer of 2000.
