Friedrich Schilling (mathematician)
Friedrich Georg Schilling (born April 9, 1868 in Hildesheim , † May 25, 1950 in Gladbeck ) was a German mathematician.
Life
From 1887, Schilling studied mathematics at the Albert Ludwig University of Freiburg and the University of Göttingen , where he received his doctorate in 1893 under Felix Klein ( contributions to the geometric theory of the Schwarz s function ). From 1891 to 1893 he was in charge of the model and instrument collection as an assistant. In 1896 he completed his habilitation in Aachen and from August 19, 1897 to April 1, 1899 was an adjunct professor at the TH Karlsruhe . From 1899 he was associate professor at the University of Göttingen, where he taught descriptive geometry and supervised the collection of mathematical devices. In 1904 he became a professor at the TH Danzig, of which he was rector from 1917 to 1919. In 1936 he retired.
In his dissertation he developed a new interpretation of the formulas of spherical trigonometry as a relationship between the invariants of three quadratic forms and their functional determinant. His theory was presented, for example, by Felix Klein in his lectures on hypergeometric functions.
He also dealt with Reuleaux tetrahedra .
Schilling worked out the lectures on higher geometry from Felix Klein from 1892/93, which were initially distributed in autograph form. In 1927 this resulted in Felix Klein's book Lectures on Non-Euclidean Geometry at Springer. Schilling himself wrote several books on non-Euclidean geometry that were strongly influenced by geometrical views. Felix Klein and Friedrich Schilling also designed geometric models that were manufactured by the Martin Schilling company in Leipzig.
In 1927 he was president of the German Mathematicians Association . In November 1933 he signed the professors' declaration of Adolf Hitler at German universities and colleges .
