Education and career

Born in Hamilton, Ontario, Arthur graduated from Upper Canada College in 1962,{{Cite web|url=http://www.ucc.on.ca/page/news-detail?pk=1230484|title=UCC community members join Order of Canada|date=January 17, 2019|website=Upper Canada College|language=en|access-date=November 19, 2019}} received a BSc from the University of Toronto in 1966, and a MSc from the same institution in 1967. He received his PhD 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.{{mathgenealogy|id=15892}}

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. He was four times a visiting scholar at the Institute for Advanced Study between 1976 and 2002.[http://www.ias.edu/people/cos/frontpage?page=5 Institute for Advanced Study: A Community of Scholars] {{webarchive|url=https://web.archive.org/web/20130106144349/http://www.ias.edu/people/cos/frontpage?page=5 |date=January 6, 2013 }}

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.{{cite web|url=https://rsc-src.ca/en/search-fellows?keywords_44=&first_name=james&last_name=arthur&display_name=&election_year_21=&academy_25=All&division_24=All&discipline_23=All&is_deceased=0&sort_by=last_name&sort_order=ASC|title=Search Fellows|author=|publisher=Royal Society of Canada|access-date=September 7, 2017|archive-date=January 31, 2019|archive-url=https://web.archive.org/web/20190131040759/https://rsc-src.ca/en/search-fellows?keywords_44=&first_name=james&last_name=arthur&display_name=&election_year_21=&academy_25=All&division_24=All&discipline_23=All&is_deceased=0&sort_by=last_name&sort_order=ASC|url-status=dead}}{{cite web|url=https://royalsociety.org/people/james-arthur-11004/|title=James Arthur|publisher=Royal Society|access-date=April 3, 2018}} In 1998 he was an Invited Speaker of the International Congress of Mathematicians in Berlin.{{cite book|author=Arthur, James|chapter=Towards a stable trace formula|title=Doc.
