on the order of convolution consistence of multivalent functions with negative coefficients

By making use of the familiar concept of modified hadamard product, or convolution, of multivalent functions with negative coefficient, combined with an integral operator, we investigate analytic function is in a given class. in the following, using the idea od u. bednarz and j. sokol, we define the order of convolution consistence of three classes of functions anddetermine a given analytic function for multivalent functions with negative coefficients.
