The question arose almost immediately whether or not such a mapping can possibly be continuous. In 1879, E. Netto put an end to such speculati

Continuous Images of a Line Segment,cterization of such sets. In 1908, A. Schoenflies found such a characterization (see Schoenflies , p. 237), which, by its very nature, only applies to sets in the two-dimensional plane. In 1913, Hans Hahn and Stefan Mazurkiewicz independently arrived at a complete characterization of such sets in
