Élie Cartan
Élie Joseph Cartan (; 9 April 1869 – 6 May 1951) was an influential French mathematician who did fundamental work in the theory of Lie groups, differential systems (coordinate-free geometric formulation of PDEs), and differential geometry. He also made significant contributions to general relativity and indirectly to quantum mechanics. He is widely regarded as one of the greatest mathematicians of the twentieth century. His son Henri Cartan was an influential mathematician working in algebraic topology. Life Élie Cartan was born 9 April 1869 in the village of Dolomieu, Isère to Joseph Cartan (1837–1917) and Anne Cottaz (1841–1927). Joseph Cartan was the village blacksmith; Élie Cartan recalled that his childhood had passed under "blows of the anvil, which started every morning from dawn", and that "his mother, during those rare minutes when she was free from taking care of the children and the house, was working with a spinning-wheel". Élie had an elder sister Je ...

Henri Cartan
Henri Paul Cartan (; 8 July 1904 – 13 August 2008) was a French mathematician who made substantial contributions to algebraic topology. He was the son of the mathematician Élie Cartan, nephew of mathematician Anna Cartan, oldest brother of composer , physicist and mathematician , and the son-in-law of physicist Pierre Weiss. Life According to his own words, Henri Cartan was interested in mathematics at a very young age, without being influenced by his family. He moved to Paris with his family after his father's appointment at Sorbonne in 1909 and he attended secondary school at Lycée Hoche in Versailles. available also at In 1923 he started studying mathematics at École Normale Supérieure, receiving an agrégation in 1926 and a doctorate in 1928. His PhD thesis, entitled ''Sur les systèmes de fonctions holomorphes a variétés linéaires lacunaires et leurs applications'', was supervised by Paul Montel. Cartan taught at Lycée Malherbe in Caen from 1928 to 1929, at Un ...

Anna Cartan
Anna Cartan (15 May 1878 – 1923) was a French mathematician, teacher and textbook author who was a student of Marie Curie and Jules Tannery. Early years Cartan was the youngest child born to Anne Florentine Cottaz (1841–1927) and Joseph Antoine Cartan (1837–1917), who was the village blacksmith. Anna had an elder sister Jeanne-Marie (1867–1931) who became a dressmaker, a brother Léon (1872–1956) who became a blacksmith working in his father's smithy, and a middle brother Élie Cartan (1869–1951) who became an acclaimed mathematician and sire of a family of mathematicians, notably his first son, Henri Cartan, who later became influential in the field. Anna's brother, Élie Cartan, later recalled that the family was very poor and his childhood had passed under "blows of the anvil, which started every morning from dawn," and that "his mother, during those rare minutes when she was free from taking care of the children and the house, was working with a spinning whe ...

Cartan (crater)
Cartan is a small lunar Lunar most commonly means "of or relating to the Moon". Lunar may also refer to: Arts and entertainment * ''Lunar'' (series), a series of video games * "Lunar" (song), by David Guetta * "Lunar", a song by Priestess from the 2009 album ''Prior t ... impact crater near the eastern edge of the Moon. It lies just to the west of the larger Apollonius. The rim is circular with a tiny crater along the eastern side. The interior floor is about half the diameter of the crater. A smaller crater attached to the southern rim is also attached to the north rim of Apollonius H, forming a short crater chain. It was named after the French mathematician Élie Cartan in 1976. Before, it was designated Apollonius D. References * * * * * * * * * * * {{Craters on the Moon: C-F Impact craters on the Moon ...
