Aleksandr Andronov

Alexander Alexandrovich Andronow (Russian Александр Александрович Андронов, scientific transliteration Aleksandr Aleksandrovich Andronov; * 29 Märzjul / April 11 1901greg in Moscow, .. † October 31, 1952 in Gorky ) was a Soviet physicist and member of the Soviet Academy of Sciences.

Life

Andronow studied from 1920 at the Technical University of Moscow and 1923-1925 Theoretical Physics at the Moscow State University. 1926-29 he continued his studies with Leonid Mandelstam Isaakowitsch while he also taught at the Second Moscow University. In 1930 he received his doctorate ( candidate). From 1931 he was a professor in Nizhny Novgorod (then Gorky ). At the same time he was at the Institute of Automation of the Soviet Academy of Sciences.

Andronow worked on quantum statistics and in particular on non-linear oscillations. His 1937 book on the subject authored with Alexander Witt and Adolfovich SEChaikin became a standard work on the perturbation theory of nonlinear systems. He also examined bifurcations, stability and topology of the solutions of dynamical systems, some with Lev Pontryagin (1937 ).

The Andronov - crater on the Moon is named after him.

He also worked with the mathematician Evgenia Alexandrovna Leontovich (later Leontovich - Andronowa ), with whom he was married.
