Stephen Schanuel

Stephen Hoel Schanuel (* July 14, 1933 in St. Louis) is an American mathematician who deals with algebra and number theory.

Schanuel studied at Princeton University (Bachelor 1955) and the University of Chicago ( Master's degree in 1956 ) and received his doctorate in 1963 at Columbia University in Serge Lang ( Heights in Number fields ). 1959 to 1961 he was instructor at the Massachusetts Institute of Technology, from 1961 to 1963 at Columbia University, and from 1963 to 1965 at Johns Hopkins University. 1965/66 he was at the Institute for Advanced Study. After that, he was a professor at Cornell ( 1965-1969 Assistant Professor ), 1969-1972 Associate Professor at the State University of New York at Stony Brook ( SUNY ) and from 1972 Associate Professor at the State University of New York at Buffalo, where he and his colleague William Lawvere worked a lot.

While still a student, he proved named after him Schanuel 's Lemma in homological algebra.

The team fielded by him conjecture of Schanuel plays a central role in the theory of transcendental numbers, because there follow many results from it. It says that when complex numbers and the numbers ( ) are linearly independent over the rational numbers, which has formed by adjoining these figures extension field of the rational numbers at least the transcendence degree. The conjecture is still unproven.

He has been married since 1958 and has two children.
