Meaning of Jordan curve theorem | Babel Free

Definitions

1. The theorem that states that a simple closed curve (Jordan curve) divides the plane into precisely two distinct areas.
2. Used other than figuratively or idiomatically: see Jordan curve, theorem.

Examples

“There is a vast generalization of the Jordan curve theorem to higher dimensions.”

“The Jordan curve theorem asserts that a simple closed curve in the complex plane divides the plane into exactly two connected components, one bounded (the "inside") and the other unbounded (the "outside" ).”

“The principal reason⟳ that orbit behavior in the plane is more limited than in higher dimensions is the Jordan curve theorem. Local sections will be the primary tool used to exploit the Jordan curve theorem.”
