A Characterization of concave mappings
V. Bravo, R. Hernández, O. Venegas
This study focuses on Concave mappings, a class of univalent functions that exhibit a unique property: they map the unit disk onto a domain whose complement is convex. The main obj…

Two-point distortion theorems for harmonic mappings
Víctor Bravo, Rodrigo Hernández, Osvaldo Venegas
We establish two-point distortion theorems for sense-preserving planar harmonic mappings which satisfies the univalence criteria in the unit disc such that, Beck…

On harmonic Bloch-type mappings
I. Efraimidis, J. Gaona, R. Hernández +1
Let be a complex-valued harmonic mapping defined in the unit disk . We introduce the following notion: we say that is a Bloch-type function if its Jacobian satis…
