Johann Peter Gustav Lejeune Dirichlet Wikipedia Johann Peter Gustav Lejeune Dirichlet February 13 May 5 ) was a German mathematician credited with the modern "formal" definition of a function His family hailed from the town of Richelet in Belgium , from which his surname "Lejeune Dirichlet" ("le jeune de Richelet" = "the young chap from Richelet") was derived, and that was where his grandfather lived. Dirichlet was born in Düren, where his father was the postmaster . He was educated in Germany , and then France , where he learnt from many of the most renowned mathematicians of the day. His first paper was on Fermat's Last Theorem . This was a famous conjecture (now proven) that stated that for n > 2, the equation x n y n z n has no solutions, apart from the trivial ones in which x y , or z is zero. He produced a partial proof for the case n = 5, which was completed by Adrien-Marie Legendre , who was one of the referees.

Prosta zasada Jaros³aw Górnicki Matematyka 5/1999 (fragment) W artykule tym pragniemy przypomnieæ twierdzenie nazywane zasad± szufladkow± Dirichleta, na cze¶æ J. P. G. Lejeune-Dirichleta (1805-1859), najwybitniejszego matematyka jaki wyk³ada³ na uniwersytecie we Wroc³awiu. Twierdzenie to powinno koniecznie by† prezentowane w szkole ¶redniej. Ma ono charakter kombinatoryczny, przy bardzo prostym sformu³owaniu prowadzi do ciekawych, niebanalnych wniosków, u³atwia rozwi±zywanie wielu trudnych zadañ. Cz³owiek i epoka Johann Peter Gustav Lejeune-Dirichlet (1805-1859) by³ znakomitym matematykiem niemieckim, pochodz±cym z rodziny francuskich emigrantów. Studia we Francji i Niemczech oraz znajomo¶æ z tej miary matematykami co Carl Friedrich Gauss, którego by³ uczniem, Carl Gustav Jacobi, Jean B. Fourier da³y mu doskona³± znajomo¶æ trendów ówczesnej matematyki. Uzyskane przez Dirichleta wyniki, nale¿±ce do szeroko rozumianej analizy matematycznej, zapewni³y mu uznanie wspó³czesnych i trwa³e miejsce w historii matematyki. W 1855 roku Dirichlet zosta³ nastêpc± Gaussa na uniwersytecie w Getyndze; wcze¶niej by³ profesorem uniwersytetów we Wroc³awiu i Berlinie. Jego uczniami byli Rudolf Lipschitz i Bernhard Riemann, który w 1859 roku zosta³ jego nastêpc± w Getyndze. Dzia³alno¶æ Lejeune-Dirichleta przypada na okres, w którym tworzy plejada wybitnych matematyków (Abel, Bolyai, Cauchy, Galois, Laplace, Poisson), a niemiecka szko³a matematyczna (Gauss, Dedekind, Kronecker, Kummer, Riemann, Weierstrass, a pó¼niej Cantor, Hilbert, Klein) nale¿y do najlepszych w ¶wiecie. Pocz±tek XIX wieku to równie¿ okres, w którym uwaga matematyków koncentruje siê wokó³ analizy matematycznej. Ten dzia³ matematyki ze wzglêdu na jego spektakularne zastosowania w naukach przyrodniczych i technicznych zapewnia matematyce pozycjê wyj±tkow± -

Johann Peter Gustav Lejeune Dirichlet Born: Died: Show birthplace location Previous (Chronologically) Next Biographies Index Previous (Alphabetically) Next Welcome page Lejeune Dirichlet proved that in any arithmetic progression with first term coprime to the difference there are infinitely many primes. Dirichlet taught at the University of Breslau in 1827 and the University of Berlin from 1828 to 1855. He then succeeded to Gauss He proved in 1826 that in any arithmetic progression with first term coprime to the difference there are infinitely many primes. This had been conjectured by Gauss His work on units in algebraic number theory (published 1863) contains important work on ideals. He also proposed in 1837 the modern definition of a function. If a variable y is so related to a variable x that whenever a numerical value is assigned to x, there is a rule according to which a unique value of y is determined, then y is said to be a function of the independent variable x. In mechanics he investigated the equilibrium of systems and potential theory. This led him to the Dirichlet problem concerning harmonic functions with given boundary conditions. Dirichlet is best known for his papers on conditions for the convergence of trigonometric series and the use of the series to represent arbitrary functions. These series had been used previously by

First recall that the sum of a finite geometric series is The first term is a ; the common ratio by which each term is multiplied to get the next is r ; the number of terms is n + 1. In particular, we have The expression to the left of "=" should make us expect the sum to be a symmetric function of r and 1/ r , but the expression to the right of "=" is perhaps less-than-obviously symmetric in those two quantities. The remedy is to multiply both the numerator and the denominator by

'At a meeting of the Accademy of Sciences..., Dirichlet presented his first paper on analytic number theory. In this memoir he gives a proof of the fundamental theorem that bears his name: Any arithmetical series of integers an + b, n = 0, 1, 2, ..., where a and b are relatively prime, must include an infinite number of primes. This result had long been conjectured and Legendre had expended considerable effort upon finding a proof, but it had been established only for a few special cases' (DSB).
