Abstract
Making use of the principle of subordination between analytic functions and a family of integral operators defined on the space of meromorphic functions, we introduce and investigate some new subclasses of meromorphic functions. Such results as inclusion relationships and integral-preserving properties associated with these subclasses are
proved. Several subordination and superordination results involving this family of integral operators are also derived.
