Özet
The purpose of the present paper is to introduce a class Dn ?;?C0(?) of bi-concave functions defined by Al-Oboudi differential op erator. 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.
