Anatoly Styopin

Anatoly Mikhailovich Styopin (Russian: Анатолий Михайлович Стёпин (may be transliterated as Stepin), 20 July 1940 – 7 November 2020) was a Soviet-Russian mathematician, specializing in dynamical systems and ergodic theory.

In 1965 he graduated from the Mechanics and Mathematics Faculty of Moscow State University.

There he received in 1968 his Ph.D. under Felix Berezin with thesis "Применение метода аппроксимации динамических систем периодическими в спектральной теории" (Application of the method of approximation of dynamical systems by periodic spectral theory) and in 1986 his Russian doctorate (Doctor Nauk) with thesis "Спектральные и метрические свойства динамических систем и групп преобразований" (Spectral and metric properties of dynamical systems and groups of transformations).

In 2009 he was awarded the title of Honorary Professor of Moscow State University.

His doctoral students include Rostislav Grigorchuk and Yiangdong Ye.
