The positive-area conjecture for non-removable curves
Let be the set of homeomorphisms of the Riemann sphere that are conformal off a curve . A curve is conformally removable if every element of is a Möbius transformation. The positive-area conjecture. If is a non-removable curve, then there exists such that has positive area. This conjecture has been open for over 30 years and is proved in the paper for the generic class of Jordan curves consisting of flexible curves.
