Jordan curve theorem wikipedia
NettetJordan's proof and another early proof by de la Vallée-Poussin were later critically analyzed and completed by Shoenflies (1924).. Due to the importance of the Jordan curve theorem in low-dimensional topology and complex analysis, it received much attention from prominent mathematicians of the first half of the 20th century.Various proofs of the … NettetThe relationship of the residue theorem to Stokes' theorem is given by the Jordan curve theorem. The general plane curve γ must first be reduced to a set of simple closed …

http://dictionary.sensagent.com/Jordan%20curve%20theorem/en-en/ NettetThe Jordan curve theorem was independently generalized to higher dimensions by H. Lebesgue and L.E.J. Brouwer in 1911, resulting in the Jordan–Brouwer separation theorem. Let X be a topological sphere in the ( n +1)-dimensional Euclidean space Rn +1, i.e. the image of an injective continuous mapping of the n -sphere Sn into Rn +1.

However, he subsequently produced three other proofs, the last one in 1849 being generally rigorous. His attempts clarified the concept of complex numbers considerably along the way.
