On certain subclasses of meromorphic functions associated with certain integral operators

Let Σ denote the class of functions of the form f(z)=1z+∑k=1∞akzk which are analytic in 0<|z|<10<|z|<1. Two new integral operators Pβα and Qβα defined on Σ are introduced. This paper gives some subordination and convolution properties of certain subclasses of meromorphic functions which are defined by the previously-mentioned integral operators.
