A Special Class of Harmonic Univalent Functions

Sarajevo Journal of Mathematics
We define and investigate a special class of Salagean-type harmonic univalent functions in the open unit disk. We obtain coefficient conditions, extreme points, distortion bounds, convex combinations for the above class of harmonic univalent functions.

Starlikeness and close-to-convexity involving certain differential inequalities

Studia Universitatis Babeş-Bolyai. Mathematica
In the present paper, we study certain differential inequalities involving meromorphic functions in the open unit disk and obtain certain sufficient conditions for starlikeness and close-to-convexity of meromorphic functions.
