Friedrich Schottky

Friedrich Schottky ( born July 24, 1851 in Breslau, † August 12, 1935 in Berlin) was a German mathematician.

Life

Father, Dr. Hermann Friedrich Schottky was "Teacher of English ". Son Frederick visited in Breslau in 1860, the Mary Magdalene school. He and Max Grube, Heinrich Rosin, Eberhard Gothein and others had founded on the Magdalenäum the literary covenant " Concordia ". The magazine, to which they cooperated, had the programmatic title: "Education of youth by itself." After high school studied Schottky 1870-1874 Mathematics at the University of Breslau. Then he went to the professors Karl Weierstrass and Hermann von Helmholtz at the Humboldt University in Berlin, where he received his doctorate in 1875. His work entitled "On the conformal representation multiply connected planar surfaces " is recognized as a historical thesis. 1878 Schottky habilitated at the Philosophical Faculty of the University of Breslau. One of the disputants was Eberhard Gothein.

Schottky taught from 1878 to 1882 as a lecturer at the University of Breslau. In 1882 he was appointed professor of higher mathematics at the Swiss Federal Institute of Technology Zurich. Here he remained ten years. In 1892 he was appointed professor at the University of Marburg. After another ten years, he returned in 1902 to Berlin, where he was a respected mathematician worked until his retirement in 1922. Since 1900, Schottky was a corresponding and ordinary since 1902 a member of the Prussian Academy of Sciences in Berlin. Among his students were Henry Young, Paul Koebe, Leon Lichtenstein, Chaim Muntz, Robert Jentzsch and Konrad Knopp.

Schottky died at the age of 84 years. The Funeral in Berlin- Steglitz took place in the immediate family. He had one daughter and four sons, including the physicist Walter Schottky ( 1886-1976 ).

Work

The focus of his work is the elliptic functions, Abelian functions and theta functions. He has published 55 papers and the book " outline of a theory of Abelian functions of three variables ". For functional theory and to questions of conformal mapping Schottky made ​​major contributions. His generalization of the theorems of Charles Emile Picard and mathematician Edmund Landau call the " set of Schottky ".

According to him, the Schottky problem of characterizing the Jacobian varieties is named among the abelian varieties. It was solved by Takahiro Shiota in 1986 but is still subject of research.
