Rufus Isaacs (mathematician)

from Wikipedia, the free encyclopedia

Rufus Philip Isaacs (born June 11, 1914 in New York City , † 1977 ) was an American mathematician who dealt with game theory.

Life

Isaacs studied engineering at the Massachusetts Institute of Technology (MIT) with a bachelor's degree in 1936, and at Columbia University , where he made his master's degree in mathematics in 1940 and received his doctorate in 1942 under Edward Kasner ( A finite difference function theory ). Until 1947 he was at the University of Notre Dame and from 1948 to 1955 at the RAND Corporation . He then worked as a mathematician for companies in the aircraft industry, the Institute for Defense Analyzes and the Center for Naval Analyzes . From 1967 to 1977 he was Professor of Applied Mathematics at Johns Hopkins University .

He is best known for his work in game theory, especially differential games, the study of which he founded. Work began at Rand Corporation, but was mostly classified at the time, and his monograph on differential games did not appear until a decade later in 1963 (for which he received the Lancaster Prize in 1965). At Rand Corporation he worked with John Milnor , John Nash , Lloyd S. Shapley , David Blackwell and Richard Bellman , among others . He also worked with Bellman in the field of dynamic optimization, founded in the west by Bellman, and in 1954/55 he found a version of the maximum principle named after Lev Pontryagin .

He had been married since 1942 and had two daughters.
