Graph Weldings Associated with Functions in Zygmund, , , and
Katsuhiko Matsuzaki, Fei Tao
Let be a continuous function. We define the graph welding associated with as the homeomorphism \[ φ= G^{-1}\circ F\colon \mathbb{R}\to\mathbb{…

Boundary Characterizations of Little Bloch and Functions on the Half-Plane
Katsuhiko Matsuzaki, Fei Tao
We extend Pommerenke's characterizations of boundary curves of conformal mappings in terms of the little Bloch and conditions from the unit disk to the…

Characterization of Asymptotically Smooth Curves
Katsuhiko Matsuzaki, Fei Tao
We construct an explicit example of an asymptotically conformal chord-arc curve that fails to be asymptotically smooth. This implies that a function belonging to both the little Bl…
