The purpose of the present paper is to investigate some inclusion properties of certain classes
of meromorphic functions associated with a family of linear operators, which are defined by
means of the Hadamard product (or convolution). Some invariant properties under convolution
are also considered for the classes presented here. The results presented here include
several previous known results as their special cases.
