arthur moritz schoenflies









































arthur moritz schoenflies (; 17 april 1853 – 27 may 1928), sometimes written as schönflies, was a german mathematician, known for his contributions to the application of group theory to crystallography, and for work in topology.









































schoenflies was born in landsberg an der warthe (modern gorzów, poland). he studied under ernst kummer and karl weierstrass, and was influenced by felix klein.









































the schoenflies problem is to prove that an formula_1-sphere in euclidean "n"-space bounds a topological ball, however embedded. this question is much more subtle than it initially appears.
