Radius Properties of Harmonic Mappings with Fixed Analytic Part

Complex Variables 2022-08-02 v1

Abstract

We investigate harmonic mappings f=h+gˉf=h+\bar{g} defined in the unit disk, where gg and hh satisfy certain prescribed conditions and the analytic part hh belongs to the Ma and Minda class of starlike functions. Certain sharp radius results for univalency, close-to-convexity, fully starlikeness, fully convexity, and radius of strongly starlikeness are established. We also calculate the radius of uniformly starlikeness and convexity for these functions. Several results enhance the well-known radius results.
