Rudolf Lipschitz

Rudolf Otto Sigismund Lipschitz (born May 14, 1832 in Königsberg i. Pr. , † October 7, 1903 in Bonn ) was a German mathematician and university professor.

Life

Lipschitz studied mathematics at the Albertus University in Königsberg from 1847 and became a member of the Corps Littuania . Later he went to the Friedrich Wilhelm University in Berlin and received his doctorate in 1853 with Gustav Dirichlet and Martin Ohm to Dr. phil. He became a private lecturer in Berlin in 1857 and married Ida Pascha . In 1862 he was appointed associate professor at the Silesian Friedrich Wilhelms University in Breslau . In 1864 he received the chair at the Rheinische Friedrich-Wilhelms-Universität Bonn . There was Felix Klein one of his students and for a time his assistant. For the academic year 1874/75 he was elected rector of Bonn University. In his rector's speech on October 18, 1874, he dealt with science and the state.

Lipschitz worked in almost all areas of pure and applied mathematics. In particular, he became known for his textbook on analysis (2 volumes, Bonn 1877 and 1880). The concept of Lipschitz continuity that he developed is still of particular importance today . He also did research in the field of differential forms and mechanics , in particular the Hamilton-Jacobian method for solving equations of motion . In addition, a convergence criterion for Fourier series is named after him.

He is buried in the Poppelsdorf cemetery .

In 1959, the Annals of Mathematics published a letter to the editor supposedly written in Hades von Lipschitz. The author is pleased that one is again interested in the Clifford algebras . He also points to some results from his research on the sums of squares that are better than those rediscovered up to 1959.
