Cameron Leigh Stewart

Cameron Leigh Stewart (c. 1949) is a Canadian mathematician who deals with number theory.

Stewart studied at the University of British Columbia with a Bachelor 's degree in 1971 and at McGill University with a master's degree in 1972 and his doctorate in 1976 with Alan Baker at the University of Cambridge (divisor properties of arithmetical sequences). At Cambridge, he was awarded the Knight TJ Prize 1974. As a post - graduate student, he was 1976/77 at the Mathematisch Centrum in Amsterdam and 1977/78 at the IHES. In 1978 he became assistant professor, associate professor in 1982 and 1986, a professor at the University of Waterloo. From 2003, he has a Canada Research Chair and he was University Professor in 2005.

He was a visiting scientist in Basel, Geneva, Ulm, Leiden, Bordeaux, at the Mathematical Sciences Research Institute ( MSRI ), the IHES, the Mathematical Institute of the Hungarian Academy of Sciences, at the Erwin Schrödinger Institute in Vienna, at the University of Colorado Boulder and the Hong Kong University of Science and Technology.

He has published, among other things on the abc conjecture. Stewart published several times with Paul Erdős and therefore has Erdős number 1

In 2008 he became a Fellow of the Fields Institute, and in 1989 a Fellow of the Royal Society of Canada.
