Ernest Arthur Michael (born August 26, 1925 in Zurich , † April 29, 2013 in Seattle ) was an American mathematician .

Michael's main area of ​​work was set- theoretical topology and there specifically the theory of continuous intersections of set- valued maps that he founded . His best known result in this area is the Michael intersection theorem . In addition, the Michael straight line and the Arens-Michael decomposition are associated with his name.

Life

Ernest Michael was born in Zurich to German-Jewish parents and grew up in Frankfurt am Main and Berlin . In anticipation of the Nazis' takeover, he and his family emigrated to the Netherlands in 1932 and then to the USA in 1939. At the age of 15 he graduated from high school there in 1941 and initially studied civil engineering at Cornell University . A year later he finally turned to mathematics. After an interruption of his studies from 1944 to 1946 caused by a war mission in the Navy , he made his BA degree at Cornell University in 1947 and in 1948 at Harvard his MA degree. At the University of Chicago he received his doctorate in 1951 with the thesis " Locally m-Convex Algebras " with Irving Segal . In 1953 he joined the University of Washington as an Assistant Professor , was Associate Professor in 1956, Full Professor in 1963 and stayed there until his retirement in 1993. He was a Fellow of the American Mathematical Society .
