Education and career

Born in Hamilton, Ontario, Arthur graduated from Upper Canada College in 1962,[3] received a B.Sc. from the University of Toronto in 1966, and a M.Sc. from the same institution in 1967. He received his Ph.D. from Yale University in 1970. He was a student of Robert Langlands; his dissertation was Analysis of Tempered Distributions on Semisimple Lie Groups of Real Rank One.[4]

Arthur taught at Yale from 1970 until 1976. He joined the faculty of Duke University in 1976. He has been a professor at the University of Toronto since 1978.[1] He was four times a visiting scholar at the Institute for Advanced Study between 1976 and 2002.[5]

Contributions

Arthur is known for the Arthur–Selberg trace formula, generalizing the Selberg trace formula from the rank-one case (due to Selberg himself) to general reductive groups, one of the most important tools for research on the Langlands program. He also introduced the Arthur conjectures.

Recognition

Arthur was elected a Fellow of the Royal Society of Canada in 1981 and a Fellow of the Royal Society in 1992.[6][7] In 1998 he was an Invited Speaker of the International Congress of Mathematicians in Berlin.[8] He was elected a Foreign Honorary Member of the American Academy of Arts and Sciences in 2003.[9] In 2012 he became a fellow of the American Mathematical Society.[10] He was elected as a fellow of the Canadian Mathematical Society in 2019.[11]
