On certain subclasses of meromorphic functions associated with certain integral operators
Let ? denote the class of functions of the form f ( z ) = 1 z + ? k = 1 ? a k z k whichare analytic in 0<|z|<1 0 < | z | < 1 . Two new integral operators P ? ? and Q ? ? defined on ? are introduced. This paper gives some subordination and convolution properties of certain subclasses of meromorphic functions which are defined bythe previously-mentioned integral operators.
