Properties of certain subclasses of meromorphic functions with positive coefficients

In this paper, we obtain coefficient estimates, distortion theorem, radii of starlikeness and convexity for the class Σ m ∗ ( a , c , A , B , α ) of meromorphic functions with positive coefficients. Some properties of neighborhoods of functions in the class Σ m ∗ ( a , c , A , B , α ) are investigated. Also we derive many results for the Hadamard products of functions belonging to the class Σ m ∗ ( a , c , A , B , α ) .
