An elementary counterexample to a coefficient conjecture
Liulan Li, Saminathan Ponnusamy, Karl-Joachim Wirths
In this article, we consider the family of functions meromorphic in the unit disk $\ID=\{z :\,|z| < 1\}$ with a pole at the point , a Taylor expansion \[f(z)= z+\sum_{k=2}…
Gromov hyperbolicity in the free quasiworld. I
Qingshan Zhou, Saminathan Ponnusamy
With the aid of a Gromov hyperbolic characterization of uniform domains, we first give an affirmative answer to an open question arisen by Väisälä under weaker assumption. Next, we…
Bloch and Landau type theorems for pluriharmonic mappings
Ming-Sheng Liu, Saminathan Ponnusamy
In this paper, we establish two new versions of Landau-type theorems for pluriharmonic mappings with a bounded distortion. Then using these results, we derive three Bloch-type theo…
A note on -bilipschitz mappings in quasiconvex metric spaces
Tiantian Guan, Saminathan Ponnusamy, Qingshan Zhou
This paper focuses on properties of \partial-biLipschitz mappings which were recently introduced by Bulter. We establish several characterizations for the class of \partial-biLipsc…
