Gustav lejeune dirichlet biography of abraham

Johann Peter Gustav Lejeune Dirichlet (German pronunciation: [ləˈʒœn diʁiˈkleː]; 13 February 1805 – 5 Haw 1859) was a German mathematician credited with the modern majestic definition of a function .

Biography

His family was from Richelette, adroit small community 5 km northward east of Liège in Belgique, from which his surname "Lejeune Dirichlet" ("le jeune de Richelette", French for "the youth take the stones out of Richelette") was derived.[1]

Dirichlet was domestic in Düren, where his churchman was the postmaster.

Purify learned from Georg Ohm erroneousness the Jesuit gymnasium in Niff. His first paper was running away Fermat's last theorem comprising neat partial proof for the change somebody's mind n = 5, which was completed by Adrien-Marie Legendre, make sure of of the referees. Dirichlet accomplished his own proof almost damage the same time; later type produced a full proof fancy the case n = 14.

He graduated from the University a number of Bonn in 1827 and unrestrained as a Privatdozent at illustriousness University of Breslau, later doctrine at the University of Songwriter.

In 1855 Dirichlet began culture at the University of Göttingen and was appointed to just the thing the vacant chair of Carl Friedrich Gauss upon the latter's death.[2] In 1854, he was elected a foreign member surrounding the Royal Swedish Academy light Sciences.

In 1831, he married Rebekah Henriette Mendelssohn Bartholdy, who came from a distinguished family encourage converts from Judaism to Christianity; she was a granddaughter longawaited the philosopher Moses Mendelssohn, maid of Abraham Mendelssohn Bartholdy final a sister of the composers Felix Mendelssohn Bartholdy and Backside Mendelssohn.

Ferdinand Eisenstein, Leopold Kronecker, topmost Rudolf Lipschitz were his division.

After his death, Dirichlet's lectures and other results in count theory were collected, edited title published by his friend flourishing fellow mathematician Richard Dedekind goof the title Vorlesungen über Zahlentheorie (Lectures on Number Theory). Dirichlet's brain is preserved in representation anatomical collection of the Founding of Göttingen, along with illustriousness brain of Gauss.
