polylogarithm function

In this paper, we introduce a new operator Ωc g(z) associated with polylogarithm function, applying it on the subclasses AHΣ∗ B (γ, k) of meromorphic starlike bi-univalent functions of order γ, and AHΣe∗ B (γ, k) of meromorphic strongly starlike bi-univalent functions of order γ, also we find estimates on the coefficients |b0| and |b1| for functions in these subclasses.
