Some Properties of a Subclass Involving Close - to - Convex of Univalent and Multivalent Functions

Our work included studying some subclasses of functions (univalent - multivalent) that are close to convex. which is divide into two parts. First part, we discussed the properties of parameter estimates, the implication relation, distortion theorem, and the radius of convexity of functions a subclass of univalent. Second part of this article, we discuss the same properties for subclasses of multivalent functions defined using the Salagen operator in the unit disc.
