In this paper, we introduced a new subclass of meromorphic functions with residue, which is defined by means of a Hadamard product (or convolution). Then we determine some properties such as coefficient bound, distortion theorems, radius of starlikeness and convexity for this class.


Key words: Analytic, meromorphic functions, Hadamard product, convolution.
