Jean-Marie Le Roux (4 April 1863, Prat, Côtes-d'Armor – 1949, Rennes) was a French applied mathematician.
Le Roux, the son of farmers, studied at the University of Rennes and, possibly, at the University of Bordeaux. He was an instructor at Guingamp from 1882 to 1889, a professor at the lycéeatBrest from 1889 to 1896, and a professor at the lycéeatMontpellier from 1896 to 1898. At the University of Rennes he became in 1898 a maître de conférences and in 1902 a professor of applied mathematics. He retired there in 1933 as professor emeritus with the title of professeur honoraire. He passed his agrégation examination in mathematics in 1889. He received his doctorate in 1894 at the Sorbonne, with Gaston Darboux, Gabriel Koenigs and Paul Appell on his thesis committee. The title of Le Roux's doctoral dissertation is Sur les intégrales des équations linéaires aux dérivées partielles du second ordre à deux variables indépendantes.[1]
Le Roux did research on partial differential equations, integral equations, and differential geometry. For the French edition of Klein's encyclopedia he edited the article WahrscheinlichkeitstheoriebyEmanuel Czuber. In 1924 Le Roux was a Plenary Speaker at the ICM in Toronto.[1][2]
