          |  |  | Abstract: |  Making use of a linear operator, which is defined here by means of the Hadamard product (or convolution), we introduce a class   of analytic and multivalent functions in the open unit disk. An inclusion relation and a convolution property for the class  are presented. Some integral-preserving properties are also given. |
