Coefficient inequalities for new subclasses of bi-univalent functions defined by using the function <i>f</i><sub>δ</sub>
Abstract
In this investigation, we introduce and study two new subclasses of bi-univalent functions defined by using the function f(delta) and Salagean differential operator. Furthermore, we find estimates on the coefficients vertical bar a(2)vertical bar and vertical bar a(3)vertical bar for these function classes.
