Faber polynomial coefficient estimates for subclass of bi-univalent functions defined by quasi-subordinate

摘要

In this paper, we use the Faber polynomial expansion to find upper bounds for |an| (n a?￥ 3) coefficients of functions belong to classes Hq?￡(??,h),STq?￡(?±,h)a??andMq?￡(?±,h) which are defined by quasi-subordinations in the open unit disk e???. Further, we generalize some of the previously published results.
