ON A CERTAIN CONVOLUTION OPERATOR FOR MEROMORPHIC FUNCTIONS
Keywords:Convolution operator, meromophic functions
A certain convolution operator $D^\alpha f(z)$ for meromorphic functions and two subclasses $M(\alpha)$ and $J(\alpha)$ are introduced. The object of the present paper is to derive some properties of the classes $M(\alpha)$ and $J(\alpha)$. The results of the paper are the generalizations and the improvements of the former results.
