Uniform iteration conjecture for essentially linear fractional self-maps of the disk

About 5 years old · traced to

Let D\mathbb{D} be the open unit disk, and let φ\varphi be an essentially linear fractional self-map of D\mathbb{D} with exactly one fixed point ww in D‾\overline{\mathbb{D}}. Uniform iteration conjecture. Then φ\varphi converges under iteration to ww uniformly on all of D\mathbb{D}. This conjecture concerns the relationship between uniformly convergent iteration and essentially linear fractional self-maps. The paper gives examples showing that these two classes do not coincide, but notes that their intersection is non-trivial; the conjectured implication remains open in the supplied source.
