ABSTRACT

In this paper, we introduce new classes, $MB_k(\alpha,\lambda,q,s,\rho)$ and $MT_k(\alpha, \lambda, q, s, \rho)$ 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 $MB_k(\alpha, \lambda, q, s, \rho)$.
