Coefficient estimates for a subclass of bi-univalent functions associated with Salagean differential operator

In this paper, we introduce and investigate a new subclass of the function class of analytic and biunivalent functions defind in the open unit disk U, which is associated with the Salagean differential operator. Furthermore, we find estimates on the Taylor-Maclaurin coefficients ja2j and ja3j of functions in the new class and improve some recent works.
