Vladimir Mikhailovich Alekseev (Владимир Михайлович Алексеев, sometimes transliterated as "Alexeyev" or "Alexeev", 17 June 1932, Bykovo, Ramensky District, Moscow Oblast – 1 December 1980) was a Russian mathematician who specialized in celestial mechanics and dynamical systems.
From 1950 he studied at the Faculty of Mathematics and Mechanics at the Moscow State University, where he worked as a student of Andrei Kolmogorov on the asymptotic behavior in the three-body problem of celestial mechanics.
Already as an undergraduate, Alekseev proved significant new results on quasi-random motion associated with the three-body problem.
[1] In 1970 Alekseev was an Invited Speaker with talk Sur l´allure finale du mouvement dans le problème de trois corps at the ICM in Nice.
[2] Over a 20-year period, he conducted 3 ongoing seminars: with Yakov Sinai on dynamical systems, with V. A. Egorov on celestial mechanics, and with M. Zelikin and V. M. Tikhomirov on variational problems and optimal control.
