چکیده
|
In this present article, the q-derivative operator and the subordination principle are use to define a class of functions that are analytic and bi-univalent in the open unit disk. our aim for this class is to obtain the upper bound for the second hankel determinant for functions in this new subclass of analytic and bi-univalent functions.
