On the class of multivalent analytic functions defined by differential operator for derivative of first order

Abstract

           In the submitted search ,by making use of Differential operator ,we drive coefficient bounds and some important properties of the subclass    ( ) of analytic

and multivalent function with negative coefficients .Distortion property for functions in the class  are investigated once by using the composition  involving an integral operator and certain fractional calculus operator and other once by using the composition  involving an integral operator and certain fractional calculus inverse operator .
