Some Subclasses of Spirallike Multivalent Functions Associated with a Differential Operator

In this paper we study convolution properties of spirallike multivalent functions defined by using a differential operator and higher order derivatives. Using convolution product relations we determine necessary and sufficient conditions for multivalent functions to belong to these classes, and our...
