چکیده
|
In this paper, we investigate on two new subclasses s∗σ(a, b) and νσ(a, b) of σ consisting of analytic and bi-univalent functions satisfying subordinations in the open unit disk u. we consider the fekete-szeg¨o inequalities for these new subclasses. also, we establish estimates for the coefficient for these subclasses.
