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

Abstract EN

In the submitted search ,by making use of Differential operator ,we drive coefficient bounds and some important properties of the subclass Ti (n,p,q,a, A) (P,j E N= {1,2,...}; q,n,E N0=N U {0};0<= a < p-q 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 .
