On certain subclasses of p-valent functions with negative coefficients defined by a generalized differential operator

In this article, we introduce new subclasses of normalized analytic functions in the unit disk U , defined by a generalized Raducanu-Orhan differential Operator. Various results are driven including coefficient inequalities, growth and distortion theorem, closure property, δ $ -neighborhoods, extreme points, radii of close-to-convexity, starlikeness and convexity for these subclasses.
