Partial sums of starlike harmonic univalent functions. (English) Zbl 1206.30030
Summary: Although interesting properties of the partial sums of analytic univalent functions have been investigated extensively by several researchers, analogous results for the partial sums of harmonic univalent functions are not yet established so far. The main purpose of the present paper is to establish some new and interesting results on the ratio of a starlike harmonic univalent function to its sequence of partial sums.
