Nikolay Nikolayevich Krasovsky ((ロシア語:Никола́й Никола́евич Красо́вский); September 7, 1924 – April 4, 2012) was a prominent Russian mathematician who worked in the mathematical theory of control, the theory of dynamical systems, and the theory of differential games.〔http://www.uralweb.ru/news/n390967.html〕 He was the author of Krasovskii-LaSalle principle and the chief of the Ural scientific school in mathematical theory of control and the theory of differential games. ==Biography== Nikolay Krasovsky was born in Sverdlovsk, Soviet Union (now Yekaterinburg, Russia) in the family of a known doctor. In 1949, he graduated ''summa cum laude'' from the department of metallurgical science at the Ural State Technical University. In 1954, he presented his first thesis and received his ''kandidat nauk'' degree in mathematics. In 1957, he defended his second thesis for the degree of ''doktor nauk'' and became a professor of mathematics. From 1949 to 1959, he worked at the Ural State Technical University.
