On Certain Subclasses of Meromorphic Univalent Functions by Khalida Inayat Noor and Ali Muhammad

In this paper, we introduce new classes, MBk(α, λ, q, s, ρ) and MTk(α, λ, q, s, ρ) of meromorphic functions defined by using a meromorphic analougue of the Choi-Saigo-Srivastava operator for the generalized hypergeometric function and investigate a number of inclusion relationships of these classes. We also derive some interesting properties of these classes, which also includes radius problem for the class MBk(α, λ, q, s, ρ).
