Abstract :
An analytic function f defined on the open unit disk U= {z:|z| 1} is bi- univalent if the function f and its inverse f^-1 are univalent in U: Inspired by the recent work of Hamidi et al. [8], we propose to investigate the coefficient estimates for a general class of analytic and bi-univalent functions. Also, we obtain estimates on the coefficients|a2| ; |a3| and janj for functions in this class. Some earlier results are shown to be special cases of our results.
Keywords :
analytic and univalent functions , bi , univalent functions , Salagean derivative
