Abstract :In this paper, estimates for second and third MacLaurin coefficients of a new subclass of analytic and bi-univalent functions in the open unit disk are determined, and certain special cases are also indicated
Keywords : Univalent functions, bi univalent functions, bi starlike function, biconvex function, functions with bounded boundary rotation, coffecient estimates, q derivativeoperator
