Abstract
The purpose of the present paper is to introduce a class D^n Σ;δ C0(α) of bi-concave functions defined by Al-Oboudi differential operator. We find estimates on the Taylor-Maclaurin coefficients |a2| and |a3| for functions in this class. Several consequences of these results are also pointed out in the form of corollaries.
