Dirichlet, (Peter Gustav) Lejeune German mathematician whose work in applying analytical techniques to mathematical theory resulted in the fundamental development of the theory of numbers. He was also a physicist interested in dynamics. Dirichlet's papers included studies on quadratic forms, the number theory of irrational fields (including the integral complex numbers), and the theory of units. His most important work was on the convergence of the Fourier series, which led him to the modern notion of a generalized function. In 1837 he presented his first paper on analytic number theory, proving Dirichlet's theorem: in every arithmetical sequence a, a + d, a + 2d, and so on, where a and d are relatively prime (that is, have no common divisors other than 1), there is an infinite number of prime numbers. Dirichlet applied his mathematical knowledge to various aspects of physics, such as an analysis of vibrating strings, and to astronomy in a critique of the ideas about the stability of the solar system proposed by French mathematician Pierre Laplace.

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).

Johann Peter Gustav Lejeune Dirichlet Fecha de primera versión: 14-10-00 Fecha de última actualización: 14-10-00 Nació: 13 de febrero en Düren, Francia (ahora Alemania) Murió: 5 de mayo de 1859 en Göttingen, Hanover (ahora Alemania) La familia de Dirichlet era originaria de Richelet, cerca de Lieja (Bélgica). Esta es la razón de su nombre "Le jeune de Richelet" (el joven de Richelet). Su padre era el cartero de Düren, un pueblo a medio camino entre Colonia y Aachen. La pasión por las matemáticas de Dirichlet fue muy temprana. Cuentan que antes de empezar los estudios en el Gymnasium (con doce años) se gastaba su dinero en libros de matemáticas. En el Gymnasium fue un alumno excelente. Después de dos años en el Gymnasium, en Bonn, sus padres decidieron enviarlo al colegio de los jesuitas en Colonia, donde tuvo la suerte de tener como profesor a Ohm. A los 16 terminó sus estudios e inició los estudios universitarios en Paris, porque el nivel de las universidades alemanas no era bueno en aquella época. Curiosamente, años más tarde, y en parte debido a Dirichlet, las universidades alemanas eran las mejores. Dirichlet llegó a París llevando consigo el libro Disquisitiones aritmeticae , de Gauss . Dirichlet siempre llevaba este libro consigo. En París contrajo la viruela. Tuvo la suerte de tener como profesores a los principales matemáticos de la época Fourier Laplace Legendre En el verano de 1823 Dirichlet fue contratado por el General Maximiliano Sebastian Foy, para la educación de sus hijos. Vivía en su casa y era tratado como un miembro de la familia. Foy había sido un personaje importante en el ejercito durante las guerras Napoleónicas. Se retiró después de la derrota de Waterloo y en 1819 fue elegido diputado, por el partido liberal.

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

Johann Dirichlet Johann Peter Gustav Lejeune Dirichlet was the first mathematician to demonstrate that in a mathematical progression with the first term acting as the coprime to the difference, there are an infinite number of prime numbers. Born on February 13, 1805 in Duren, Germany . In 1826, Dirichlet proved the aforementioned statement which was a conjecture of Karl Gauss. Furthermore, he contributed a great deal to Algebraic number theory and in 1837 proposed the modern definition of a function. The latter was a great accomplishment as it set the parameters for all sorts of modern analytical mathematics. As a consequence, non-Euclidean geometry had less rigid parameters to work from. Dirichlet is probably most famous for his work on convergence of trigonometric series and the use of arbitrary functions The following is Dirichlet's 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." From 1828-1855, Dirichlet taught at the University of Berlin. Thereafter, Dirichlet succeeded the presitgious

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.

Zabýval se øešením Fermatova teorému (neexistence øešení rovnice x n y n z n v celoèíselném oboru) pro n = 5 a 14. Studoval polynomiální rovnice a intenzivnì se zabýval teorií èísel. V mechanice studoval potenciály rovnovážných systémù. Hledal øešení Laplaceovy rovnice s pevnì danými okrajovými podmínkami (dnes nazývanými Dirichletovy podmínky).

Johann Peter Gustav Lejeune Dirichlet Lejeune Dirichlet's family came from the Belgian town of Richelet where Dirichlet's grandfather lived. His father was the postmaster of Düren, the town of his birth situated about halfway between Aachen and Cologne. Even before he entered the Gymnasium in Bonn in 1817, at the age of 12, he had developed a passion for mathematics and spent his pocket money on buying mathematics books. Return to main page
