Robert Daniel Carmichael

Robert Daniel Carmichael (born March 1, 1879 in Goodwater , Alabama , † May 2, 1967 in Merriam , Kansas ) was an American mathematician .

Life

Carmichael attended Lineville College in Alabama with the Bachelor graduation in 1898 and then was Presbyterian minister in Hartselle , Alabama. From 1905 he began to publish problems in the American Mathematical Monthly and essays in mathematical journals and in 1905 he became a mathematics professor at Presbyterian College, Anniston . After he had published 170 papers, including in the Annals of Mathematics and the Bulletin of the American Mathematical Society , he continued his studies at Princeton University fort, where he in 1911 George David Birkhoff Ph.D.(Linear Difference Equations and their Analytic Solutions). As a student he received the Porter Ogden Jacobus Fellowship at Princeton. After receiving his doctorate, he became an assistant professor and in 1912 an associate professor at Indiana University . In 1915 he taught at the University of Chicago Summer School, became an assistant professor at the University of Illinois , in 1918 an associate professor and in 1920 he was given a full professorship . From 1929 to 1934 he headed the mathematics faculty and was dean of the graduate school from 1934, which he remained until his retirement in 1947.

Carmichael was considered a talented and versatile mathematician. The set of Carmichael dates back to 1910. He published in 1914 and 1915 two books on number theory and a book on group theory . The Carmichael function comes from him and the Carmichael numbers are named after him .

From 1912 he also dealt with the theory of relativity , about which he published a book in 1913. The material was based on lectures he gave at the University of Indiana in the fall of 1912, as well as his publications in Physical Review . He took into account the development of the general theory of relativity by Albert Einstein in the 2nd edition in 1920.
