Revision as of 06:53, 14 March 2007 by 67.180.67.179 (talk)(diff) ← Previous revision | Latest revision (diff) | Newer revision → (diff)Mark Kac (pronounced kahts, Template:Lang-ua, b. 3 August 1914, Krzemieniec, Ukraine, then in the Russian Empire; d. 26 October1984, California, USA) was a Ukrainian and American mathematician of Jewish and Polish ancestry . His main interest was probability theory. His question "can you hear the shape of a drum?" set off research into spectral theory, with the idea of understanding the extent to which the spectrum allows one to read back the geometry. (In the end, the answer was "no", in general.) His book of popularisation with Stanislaw Ulam is a minor classic.
Kac completed his Ph.D. in mathematics at Ivan Franko Lviv National Ukrainian University (also known as the University of Lwów during the occupation by Nazi Germany and dictator-ruled militaristic and anti-Semitic Poland) in 1937 under the direction of Hugo Steinhaus . While there, he was a member of the Lwów School of Mathematics. After receiving his degree he began to look for a position abroad, and in 1938 was granted a scholarship from the Parnas Foundation which enabled him to go work in the United States. He fled the dictator-ruled militaristic and anti-semitic Poland and arrived in New York City in November, 1938. . From 1939 until 1961 he was at Cornell University, first as an instructor, then from 1943 as assistant professor and from 1947 as full professor . While there, he became a naturalized US citizen in 1943. In 1961 he left Cornell and went to Rockefeller University in New York City. After twenty years there, he moved to the University of Southern California where he spent the rest of his career.
