Prove Jordan Curve TheoremSome tough topology. I have discovered a truly marvellous signature, which this margin is too narrow to contain. Fermat Give me a lever long enough and a fulcrum on which to place it, and I shall move the world. Archimedes Young man, in mathematics you don't understand things. You just get used to them.

Re: Prove Jordan Curve TheoremThat is something obvious but we still need a proof Last edited by Agnishom (20130812 12:10:16) 'And fun? If maths is fun, then getting a tooth extraction is fun.

Re: Prove Jordan Curve TheoremI do somewhat. I have discovered a truly marvellous signature, which this margin is too narrow to contain. Fermat Give me a lever long enough and a fulcrum on which to place it, and I shall move the world. Archimedes Young man, in mathematics you don't understand things. You just get used to them.

Re: Prove Jordan Curve TheoremI am still stuck at graph theory 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'
