A Discrete Proof of The General Jordan-Schoenflies Theorem

Li Chen, Steven G. Krantz

In the early 1960s, Brown and Mazur proved the general Jordan-Schoenflies theorem. This fundamental theorem states: If we embed an sphere locally flatly in an $…

A Concise Proof of Discrete Jordan Curve Theorem

Li Chen

This paper gives a concise proof of the Jordan curve theorem on discrete surfaces. We also embed the discrete surface in the 2D plane to prove the original version of the Jordan cu…
