Julius Weingarten

Julius Weingarten ( born March 25, 1836 in Berlin, † 16 June 1910 in Freiburg im Breisgau ) was a German mathematician.

Weingarten stopped after finishing school lectures at the University of Berlin, such as on potential theory with Dirichlet. In 1864 he earned his doctorate at the University of Halle.

Weingarten in 1871 professor at the School of Architecture and at the Technische Hochschule Charlottenburg. In 1905 he went for health reasons to the chair of mathematics in Freiburg im Breisgau, where the climate for his health appeared more favorable.

Weingarten edited specifically to the field of differential geometry and steered it was the first to draw attention to those areas where the main radius of curvature is a function of the other. For the calculation procedure of the European arc measurement Weingarten wrote a treatise on trigonometry on the spheroid. His most significant work is about the theory of sequential developable surfaces ( 2 vols Heidelberg 1875). His published works since 1886 to the infinitesimal deformations of surfaces were inter alia Darboux highly praised.

With a larger work on this subject Weingarten won the 1894 grand prize of the Paris Academy of Sciences. In this work he showed that it is possible all isometric to a given area of ​​land with the solutions of a partial differential equation to determine the type Monge - Ampère.

Weingarten also collaborated with the Italian mathematician Luigi Bianchi, the letters vineyard occupy the most space in the correspondence.

In his honor, named the Weingarten surfaces, the surfaces of constant mean curvature radius are. 1890 Weingarten was appointed a member of the Leopoldina.
