Lazarus Fuchs

Immanuel Lazarus Fuchs ( born May 5, 1833 in Moschin, Poznan province, † April 26, 1902 in Berlin) was a German mathematician.

Life

Fuchs studied from summer semester 1854 Mathematics at the University of Berlin, including at Ernst Eduard Kummer and Karl Weierstrass, and earned his doctorate under Weierstrass on August 2, 1858. On March 19, 1859 he took the examination for teachers at secondary schools. He worked from 1860 as a substitute teacher and from 26 March 1864 to 23 May 1867 as a teacher in Berlin, including at the Friedrich - Werder trade school.

In August 1865, he completed his habilitation at the University of Berlin, and was appointed on December 7, 1866 to associate professor. From 23 May 1867 he was also a teacher at the Artillery and Engineering School in Berlin. On February 3, 1869 Fox became a full professor at the University of Greifswald. As of March 22, 1869, he was also a lecturer at the Agricultural Academy Eldena. On January 23, 1874, he became a full professor at the University of Göttingen. On 8 January 1875, he was the successor of Leo Koenigsberger full professor at the University of Heidelberg and co-director of the Mathematics and Physics seminar. In the summer semester 1884, he returned as the successor of Karl Weierstrass a full professor at the University of Berlin, where he, together with Leopold Kronecker headed the Mathematical Seminar to 1892. In 1899 he was rector of the University of Berlin.

Fox died on 26 April 1902 in Berlin. He was buried in Schöneberg on the St. Matthew's Cemetery. The grave is located in the field H.

Work

Fox looked at the areas function theory, differential geometry and calculus of variations. He dealt primarily with algebraic and function-theoretic problems, and especially the theory of homogeneous linear differential equations of nth order in the complex domain with analytic coefficient functions ( Fuchsian differential equations).
