Béla Kerékjártó’s theorem on the topology of open surfaces. (Kerékjártó Béla tétele nyilt felületek topológiájáról.) (Hungarian)
Polygon 12, No. 1-2, 23-34 (2003).
This article deals with a theorem of Kerékjártó (1931). The author gives some topological definitions, illustrates some special surfaces, dicusses the main topological invariants, formulates the main theorem of the topology of polyhedra and deals with the topology of open surfaces. She gives Kerékjártó’s theorem on the topology of open surfaces (1931), which was generalized in 1960 by Ian Richard in his dissertation On the classification of noncompact surfaces.
