Coe cient bounds for comprehensive subclass of bi-univalent positive meromorphic functions

In this paper, we introduce and investigate an interesting subclass of mero- morphic and bi-univalent functions on Δ = fz ۲ C : ۱ < jzj < ۱g. Furthermore, for functions belonging to this class, estimates on the initial coe cients are obtained. The results presented in this paper would generalize and improve some recent works of several earlier authors.
