Initial Coefficient Estimates for Bi-Univalent Functions

On -pseudo q -bi-starlike functions

“…Ismail et al [6] introduced the class of generalized complex functions via q -calculus on some subclasses of analytic functions. Recently, Purohit and Raina [16] investigated applications of the fractional q -calculus operator to define new classes of functions that are analytic in unit disk U (see, for details, [7], [10], and [20]- [23]).…”

“…We define the Sălăgean q -differential operator (also refer to [10]) using the q -differential operator as follows:…”
