Numan Yunusovich Satimov

Numan Yunusovich Satimov (Нуман Юнусович Сатимов) (15 December 1939 – 22 September 2006) was a Soviet and Uzbek mathematician, Doktor Nauk in Physical and Mathematical Sciences, academician of the Academy of Sciences of Uzbekistan (2000), and corresponding member of the Academy of Sciences of UzSSR from 1979 to 2006, and a laureate of the Biruni State Prize (1985). He was a specialist in the theory of differential equations, control theory and their applications.

Biography
Satimov was born on 15 December 1939 in the city of Andijan in a working-class family.

In 1956, he was accepted to the Central Asian State University at the Faculty of Physics and Mathematics. In 1958, Satimov continued his studies at the Moscow State University named after M. V. Lomonosov at the Faculty of Mechanics and Mathematics. After graduating from the university in 1962, he entered graduate school at the Uzbek Academy of Sciences' Romanovsky Institute of Mathematics, where he worked as a junior research fellow from 1965 to 1968.

In 1968, under the guidance of Professor V. G. Boltyansky, Satimov defended his thesis. In 1977, under the guidance of Professor E. F. Mischenko, he defended his doctoral dissertation (at the specialized council of Steklov Institute of Mathematics). In 1978, he was awarded the title of professor. In 1979, he became a corresponding member of the Academy of Sciences of the Uzbek SSR, in 2000 – academician of the Academy of Sciences of the Republic of Uzbekistan.

Since 1968, Satimov worked in Tashkent State University. In 1971, he became the head of a department at the Faculty of Applied Mathematics and Mechanics of NUUz. From 1974 to 1976, Satimov worked as a senior research fellow at Steklov Institute of Mathematics. From 1985 to 1987 he served as the dean of the Faculty of Applied Mathematics and Mechanics. Since 2000, he was a leading researcher at the Uzbek Academy of Sciences' Romanovsky Institute of Mathematics.

Satimov died on 22 September 2006. He was buried at the Chagatai cemetery in Tashkent.

Scientific interests
Satimov's primary research interest included the theory of differential equations, control theory and their applications. He founded the Tashkent Scientific School on the theory of controls and differential games. He led the research seminar “Optimal processes and differential games” for over 35 years.

Moreover, Satimov is the author of a textbook on differential equations and two monographs. He published more than 180 scientific papers; most of which have been translated and published in US and UK journals. Under his guidance, eight doctoral and more than twenty master's theses were prepared.

Since 1970, Satimov worked on a new section of the theory of controlled processes – the theory of differential pursuit–evasion games. He paid particular attention to the development of L. S. Pontryagin's methods. As a result, Satimov proposed and later developed the so-called third (modified) method for solving the problem of persecution.
