Estimate for Initial MacLaurin Coefficients of Certain Subclasses of Bi-univalent Functions
In this paper, estimates for second and third MacLaurin coefficients of certain subclasses of bi-univalent functions in the open unit disk defined by convolution are determined, and certain special cases are also indicated. The main result extends and improve a recent one obtained by Srivastava et al.
