Juni 1925 in Göttingen) war ein deutscher Mathematiker. Felix Klein hat im 19. Jahrhundert bedeutende Ergebnisse in der Geometrie erzielt. Daneben hat er sich um die Anwendung der Mathematik und die Lehre verdient gemacht. Klein, der auch ein bedeutender Wissenschaftsorganisator war, hat wesentlich mit dafür gesorgt, dass Göttingen zu einem Zentrum der Mathematik aufgestiegen ist. Grabstelle in Göttingen Klein studierte in Bonn bei Rudolf Lipschitz und Julius Plücker, dessen Assistent er wurde. Nach dem Tod Plückers übernahm Alfred Clebsch die Herausgabe seines unvollendeten Werkes und übertrug diese Arbeit an den begabten Klein. Klein promovierte 1868 bei Lipschitz mit einem Thema aus der Geometrie angewandt auf die Mechanik. 1869 ging er dann an die Berliner Universität und hörte dort eine Vorlesung von Leopold Kronecker über quadratische Formen. Er nahm an den mathematischen Seminaren von Ernst Eduard Kummer und Karl Weierstraß teil, wo er auch Sophus Lie kennen lernte, mit dem er 1870 zu einem Studienaufenthalt nach Paris ging und befreundet war. Aufgrund des deutsch-französischen Kriegs kehrte er nach Deutschland zurück. Er habilitierte sich 1871 bei Clebsch in Göttingen und blieb 1871/72 als Privatd...http://booksllc.net/?l=de&id=31071 ...

Excerpt:"Abel's formula" redirects here. For the formula on difference operators, see Summation by parts . In mathematics , Abel's identity (also called Abel's differential equation identity ) is an equation that expresses the Wronskian of two homogeneous solutions of a second-order linear ordinary differential equation in terms of a coefficient of the original differential equation. The relation can be generalised to n -order linear ordinary differential equations. The identity is named after the Norwegian mathematician Niels Henrik Abel . Since Abel's identity relates the different linearly independent solutions of the differential equation, it can be used to find one solution from the other. It provides useful identities relating the solutions, and is also useful as a part of other techniques such as the method of variation of parameters . It is especially useful for equations such as Bessel's equation where the solutions do not have a simple analytical form, because in such cases the Wronskian is difficult to compute directly. A generalisation to first-order systems of homogeneous linear differential equations is given by Liouville's formula . Statement of Abel's identity Consider a homogeneous linear second-order ordinary differential equation on an interval I of the real line with a real - or complex -valued continuous function p . Abel's identity states that the Wronskian W ( y 1, y 2) of two real- or complex-valued solutions y 1 and y 2 of this differential equation, that is the function defined by the determinan... ...

Excerpt:Anton Wilhelm Brøgger (11 October 1884 29 August 1951) was a Norwegian archaeologist. Personal life He was born in Stockholm as a son of professor of geology Waldemar Christofer Brøgger (1851 1940) and Antonie Scheel Siewers (1854 1933). He was a grandson of the book printer Anton Wilhelm Brøgger. In September 1909 he married Inger Ursin (1882 1941). He had the sons Waldemar Christofer Brøgger (1911 1991) and Niels Christian Brøgger (1914 1966), and through the former, the grandson Jan Brøgger . Career Brøgger finished his secondary education in 1903, but his higher education was sporadic. Without a formal examination, he wrote the paper Øxer av Nøstvettypen , which was released in 1905 by the Norwegian Geological Survey . He participated in the archaeological studies of Svarthola outside Stavanger, and wrote a report from the first kitchen left-over heap from early Stone Age found in Norway, published in the annals of Stavanger Museum for 1907. Already in 1909 he took the dr.philos. degree with the thesis Den arktiske stenalder i Norge . From 1909 to 1913 he worked as a curator at Stavanger Museum . He wrote a book on the city's medieval history, and also became involved in Stavanger Aftenblad and founded the local branch of the Society for the Preservation of Ancient Norwegian Monuments . He also contributed to Dagbladet and Tidens Tegn . He was hired at Universitetets Oldsaksamling at the Royal Frederick University in 1913, and became leader of Universitetets Oldsaksamling as well as professor in 1915. He also contribu... ...
