Cofficient estimates for a general Subclass of bi-univalent functions

Abstract

‎In this paper‎, ‎we introduce and investigate an interesting subclass‎ ‎${\cal{S}}^{h,p}_{\Sigma}(A,B,C,\lambda)$ of bi-univalent functions in the open unit disk $\mathbb{U}$‎. ‎Furthermore‎, ‎we find estimates on the $|a_2|$ and $|a_3|$‎ ‎coefficients for functions in this subclass‎. ‎The coefficient bounds presented here generalize some recent works of several earlier authors‎.
