Abstract

Complex-valued harmonic functions that are univalent and sense-preserving in the unit disk D can be written in the form f = h + g, where h and g are analytic in D. We give some inequalities for normalized harmonic functions that are starlike.

Keywords

Harmonic mappings, starlike function, Caratheodory function.
