Composer
Sergei Lyapunov, mathematician
Aleksandr Lyapunov, and philologist
Boris Lyapunov were his close relatives. In 1928, Lyapunov enrolled at
Moscow State University to study mathematics, and in 1932 he became a student of
Nikolai Luzin. Under his mentorship, Lyapunov began his research in
descriptive set theory. He became world-wide known for his theorem on the range of an atomless vector-measure in finite dimensions, now called the Lyapunov Convexity Theorem. From 1934 until the early 1950s, Lyapunov was on the staff of the
Steklov Institute of Mathematics. When
Mstislav Keldysh organized the Department of Applied Mathematics (now the M.V. Keldysh Institute of Applied Mathematics) he suggested Lyapunov to lead its work on programming. In 1954 A.A. Lyapunov was invited by
Anatoly Kitov (scientific director of the Computing Center No. 1 of the USSR Ministry of Defense) to this computing center as head of the laboratory. A.A. Lyapunov worked at this military computing center until 1960. In 1961, Lyapunov moved to the Institute of Mathematics of the Siberian Division of the Academy of Sciences of the Soviet Union (now the
Sobolev Institute of Mathematics), where he founded the department of cybernetics. At
Novosibirsk State University, he founded the Department of Theoretical Cybernetics and the Laboratory of Cybernetics at the Institute of Hydrodynamics of the Siberian Division of the Academy of Sciences of the Soviet Union (now the Lavrentiev Institute of Hydrodynamics) which he led until the end of his life. In 1964, Lyapunov was elected a member of the Academy of Sciences of the Soviet Union and joined the Division of Mathematics. He was awarded the
Order of the Red Star in 1944,
Order of the Badge of Honour in 1953, two
Orders of the Red Banner of Labour (1956 and 1967), and
Order of Lenin in 1971. In 1996, he was awarded the
IEEE Computer Society's
Computer Pioneer Award. ==References==
