Arthur Moritz Schönflies
From Wikipedia, the free encyclopedia
Arthur Moritz Schönflies (April 17, 1853 – May 27, 1928) was a German mathematician, known for his contributions to the application of group theory to crystallography, and for work in topology.
Schönflies was born in Landsberg an der Warthe (modern Gorzów, Poland). He studied under Kummer and Weierstrass, and was influenced by Felix Klein.
The Schönflies problem is to prove that an (n − 1)-sphere in Euclidean n-space bounds a topological ball, however embedded. This question is much more subtle than initially appears.
He studied at the University of Berlin from 1870-1875. He obtained a doctorate in 1877, and in 1878 he was a teacher at a school in Berlin. In 1880, he went to Colmar to teach.
He was a great-uncle of Walter Benjamin.
