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