Generalization on Differential Subordination with a Subclass of Harmonic Univalent Functions

Abstract

The new class of harmonic functions that are defined in this work through the usage of subordination is being introduced. For this class of functions we find compactness, convexity, and radii of starlikeness, together with necessary and sufficient requirements. We may also derive distortion theorems and coefficient estimates for this class of functions by employing extreme point theory.
