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

Year, pages: 2018, 369 - 378

In this paper, we use the Faber polynomial expansion to find upper bounds for $|a_n|$ ($n≥ 3$) coefficients of functions belong to classes $H_q^Σ(λ,h), ST_q^Σ(α,h)$ and $M_q^Σ(α,h)$ which are defined by quasi-subordinations in the open unit disk $\mathbb{U}$. Further, we generalize some of the previously published results.
