Hadamard and quasi-Hadamard properties for certain subclasses of analytic functions

In the present paper two subclasses \mathcalSq*(\itNe) and \mathcalKq(\itNe) of analytic functions are introduced by using q-derivative operator. Several properties including Hadamard product, quasi-Hadamard product, the necessary and sufficient condition and coefficient estimates for the functions belonging to these subclasses are obtained.
