چکیده
|
In this paper, we define a class of meromorphically multivalent functions in u∗ = {z : z ∈ c : 0 < |z| < 1} by using a differential operator. important properties of this class such as coefficient estimates, distortion theorem, radius of starlikeness and convexity, closure theorems, and convolution properties are obtained. we also study δ-neighboorhoods and partial sums for this class.
